hello wonderful person this is Anton and
in today's video we're going to be
talking about Canopus the second
brightest star in the night sky that was
actually used for navigation for
centuries and surprisingly it's still
used in navigation today anyway let's
discover more about it and welcome to
what the math
so before we actually go and check out
that sir
let's land somewhere on a continent on
our planet earth and find out where this
star is located it's actually quite
visible from anywhere in the southern
hemisphere but it is only visible
partially on some months in a year from
the northern hemisphere so we might
actually have to go somewhere like
Australia or South America to try to
discover it so here's Australia and if I
were to land somewhere on this continent
let's just land right in the middle very
close to Iraq okay maybe not so close
okay I kind of missed but anyway so here
we are in Australia and we're going to
just point our selves at Canopus and
that's this really famous star it's
located right there
in that region of space now let's
actually just slowly start going toward
it this starts actually quite far away
it's about 330 no light-years away from
us and it's considered to be a kind that
was supergiant with a temperature of
about 7,000 degrees Kelvin and the total
size of about 70 times the size of our
own Sun in other words if we were to
actually try to place the star in our
solar system it would most likely reach
mercury now why are we talking about
Canopus well for one like I mentioned in
an introduction it sexually started the
ancients from many different cultures
used to orient themselves so it was
basically used for navigation this
beautiful bright star was quite visible
from pretty much anywhere in the sky and
being the second brightest star after
serious it was quite easy to see even on
nights where there would be very very
few stars in the night sky so in that
sense it was actually very very good for
you know being able to position yourself
around the region on in the southern
hemisphere and it's also kind of
relatively close to the southern pole so
sometimes it's known as
the southern polar star then or the
floor star is of course flourish it's
very very famous but this one is a
little bit least less famous mostly
because it's not directly in the south
and pole pole region but it really is
relatively close to it and it will get
even closer in about 14,000 years now
you may actually know about this star if
you read science fiction because Canopus
is the system where the infamous planet
from Frank Herbert's dune is located and
this planet is of course known as
Arrakis the planets also known as the
jun-san planet now will obviously have
some planets orbiting here and we're
going to go and check them out but I
highly doubt that any of them is going
to be a wreck it's like but we never
know and also we don't really know if
there are any planets around Canopus
just yet because we haven't really
discovered any we have haven't really
been looking very closely at or so for
all we know there might be something
around there but if I were to accelerate
time here you'd see that there's
actually quite a lot of things going on
in the system specifically planets and
asteroids and comets and stuff like that
now I actually wanted to mention this
planet because I very recently made a
video about Voyager 2 and in that video
I very briefly mentioned that Voyager 2
actually used Canopus for navigation and
not just Voyager 2 as a matter of fact a
vast majority of satellites and probes
and spacecraft use Canopus for
navigation and it's actually a brilliant
system so if you were located somewhere
in the solar system and you point
yourself at Canopus because it's throw
to the close to the southern pole and
because you're probably flying in the
direction well actually let me show you
you're probably flying somewhere in the
same plane of orbit as other planets in
our solar system so in other words you
go in somewhere this way or somewhere
along the plane and you basically just
need two points for navigation you can
look behind you and use the Sun it's on
the same planner orbit
and then you can basically look at
Canopus which is pretty much right below
you
it's in a southern hemisphere it's right
there and using these two points it's
actually very very easy to position
yourself pretty much anywhere in the
solar system so I can be somewhere right
here and I don't really know where I am
but by looking at Canopus and
establishing the actual location in
terms of degrees and then by looking at
the Sun and doing the same I can then
use the data gathered from Earth and
estimate my current location so for two
and really all of the voyagers and many
other probes including of course most of
the probes that were launched into deep
space
use both Canopus and the Sun as a kind
of a very unusual but very very cool
navigation system now this is actually
an officially known as the Canopus
tracker or Canopus tracker the Parana
were what part of english-speaking
region of the world you're from but
what's interesting is that even today we
still use the same system because it's
so effective and the only time it
actually failed was during 1974 where
Mariner 10 space craft was actually on
the way to mercury and unfortunately had
a little speck of dust on its lens that
measure it the luminosity of Canopus and
it accidentally mistook that speck for
cannabis and kept turning around and
moving around and shifting and wishing
its fuel basically but it's lucky we
didn't wasted a few and was still able
to make it back I will not make it back
but make it to mercury
but anyway so let's actually take a look
at some of the planets in this system
just for fun and as you can see there's
quite a variety and quite a lot of
various color selections and look at
that I was totally wrong there is
actually a planet known as Canopus one
then it's a torrid desertic subterra in
other words it is Arrakis we have
discovered a ruckus and this is what it
looks like in space engine welcome to
the June every
this is probably unusually the most
unusual encounter I've had in space
engine because I didn't actually think I
would have something that's from the
science-fiction present in the game but
at the same time the temperature here is
like two thousand six hundred twenty
degrees so in that sense don't expect
anything to survive on this planet
because it's a little bit too hot and it
also has a moon with a very similar
superhot temperature almost of the
planets here as you can see extra very
hot so this one here is 1600 degrees
Celsius this is Canopus too and don't
forget these are all procedurally
generated so they don't actually maybe
exist in real life but interestingly
this one has a moon that's very very
close to to the surface here so if I
accelerate time you'll see how fast it
orbits around the second planet and no
one of these objects are actually very
interesting-looking so this is a terror
like object this one here is a super
Terra or a super earth with 17 months
quite a lot of moons and quite a hot
climate of 1,500 degrees Celsius but
interestingly as we keep going we'll
eventually discover this a worm sub a
Quarrier basically a warm liquid world
with temperatures of 56 degrees Celsius
and green surface and which seems to be
so Furyk oceans of sulphur or something
not entirely sure what kind of liquid
this is but clearly not water because
it's not present on a surface the other
objects are gas giants and this one here
is another hot super aquarium so quite a
lot of really cool objects here and
quite a lot of interesting places to
visit including this object that
actually has rings and look at these
beautiful beautiful clouds let's go into
land on this one actually let's go check
it out
so interesting in fact about Carol
system is that it's actually been used
in science fiction quite a lot including
Star Trek at least two episodes and in
other books like for example the star
kings by Edmund Hamilton so this system
is actually very popular mostly because
it's such a bright star and so easy to
see in the night sky but honestly the
coolest thing about it is of course the
fact that we use it in navigation and
I'm not entirely sure what these lines
are and whether this is artificial a bug
or a feature but look at that this is
actually rings this is incredible these
are very unusual rings that simply be
spinning around this planet and create
these unusual effects but they don't
spin where you would usually find rings
so in that in that sense it's probably a
bit of a bug well that's actually just
accelerate time and see what this looks
like this is actually one of the newer
versions of space engine so there's
still some there's a few bugs here and
there this is really cool I've never
seen anything like this before
very unusual formation of rings on the
super hot planets Canopus 9 so yes the
fact that we've still use this in
navigation and the fact that there's
such an effective navigation tool is
actually what makes Canopus really
really cool and of course the fact that
it's such a bright star and so easy to
see from pretty much anywhere and has a
very specific spectrum a very specific
amount of x-ray radiation of the inmates
most of the spacecraft that use it for
navigation can easily find it in a night
sky and usually don't confuse it for
anything else and so in that sense
Canopus is actually going to be still
used quite widely especially once we
start exploring space and become a
spacefaring species but for now that's
really all i wanted to talk about in
this video and thank you so much for
watching hopefully you learned about
Canopus and now you know a little bit
more about it and if you know something
else about it that I haven't mentioned
please mention it in the comments
I'll see this the world spaced out
please subscribe he's still heavens
share this video with someone who enjoys
watching space videos and spaced out and
as always
bye bye
