welcome to lab360 for all the news and
videos from the world of space outer
space is one of the biggest unknown
entities to human beings
although space agencies around the world
do their best to try to discover things
that happen outside our planet
nasa one of the world's leading space
agencies
possesses a system called sentry which
exhaustively monitors asteroids and the
possibilities of whether or not
any could collide with earth in the next
100 years
the american space agency had considered
an asteroid called 2009 jf1
to be potentially dangerous
nasa had established the exact date and
time of a possible impact with planet
earth
may 6 2022 and the time
8 34 in the morning spanish peninsular
time
until a few days ago asteroid 2009 jf1
was present in the top 10 ranking of our
risk list
for a possible impact on may 6 2022
it is a small object only about 10
meters in diameter
and therefore the possible impact was
not of significant concern
however its probability of one in four
thousand made it one of the most likely
predicted events in our risk list
and together with its approaching impact
date attracted our attention for further
investigation
it was first found by the nasa-funded
catalina sky survey's mount lemon
station in arizona on fourth of may of
the year 2009.
unfortunately nobody else detected the
object back then
nor at any later time
in fact the time span between the first
and last observation was less than 30
hours
and resulted in a poor knowledge of the
object's orbit that made the object
effectively lost just a few weeks after
discovery
the european space agency later assessed
the accuracy of the positional
measurements to a much better level
thanks to gaia's unbiased determination
of reference systems in the sky
this new information extracted from
existing data but with new tools that
were not available at the time
was then used by the team to reassess
the impact risk posed by 2009 jf1
the results were interesting the impact
probability dropped to just one in one
million seven hundred thousand
and the asteroid has now lost its
prominence in our risk list and is
relegated together with other more
routine objects that pose minimal threat
2009 jf-1 is a small near-earth object
that should pass within 0.3 astronomical
units
45 million kilometer of earth in 2022
on february 5th 2022 the 2009
observations were re-measured greatly
reducing the odds of an impact
so yeah now on may 6 2022
it has a 1 in 140 000 chance of
impacting earth
we will only find out if the odds are
against us on may 6th
what do you guys have to say
drop in your comments to let us know and

in today's news a massive asteroid is
heading towards the earth reported nasa
the asteroid which is the size of golden
gate bridge
san francisco california is approaching
earth at a massive speed and has been
classified as an apollo class asteroid
but due to its close proximity to the
earth this near-earth object or neo has
also been labeled as a potentially
hazardous asteroid
it is a massive 450 meters wide space
rock and is expected to make its closest
approach to the earth at a distance of
two hundred forty thousand kilometers
according to the jet propulsion
laboratory by nasa the asteroid hurtling
towards the earth is named 2008 ag-33
the asteroid has a massive orbit where
one revolution takes about 18 years to
complete
the asteroid also possesses a high speed
of more than 25 000 kilometers per hour
at this speed if it were to strike the
earth it could easily flatten tens of
kilometers of land
at its closest point the asteroid
traveling at more than 30 times the
speed of sound will come within about 2
million miles
3.2 million kilometers of earth which is
roughly eight times the average distance
between earth and the moon
this may sound like a big gap but by
cosmic standards it's actually a stone's
throw away
so yes this particular asteroid seems
unlikely to strike
and is expected to make a safe passage
across the planet
however the space agency is continuing
to observe it in case a sudden deviation
happens
thank you nasa
it feels good to know that you have our
back
what do you guys have to say
