SPACE FACTS
Space is amazing. The sheer vastness of it, along with the trillions upon trillions of objects in
the many billion galaxies of the universe is almost incomprehensible to the human brain.
This page is a continuously updated list of the most incredible, awe-inspiring and
unbelievable facts about space. Whether it's for kids looking to learn more about space, or
you're looking for incredible facts for an article, or even if you just love space facts for no
real reason, this is for you.
There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.
Astronauts use radios to stay in communication while in space, since radio waves can still be sent and
received.
Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C.
Interestingly, Venus is not the closest planet to the Sun – Mercury is closer but because Mercury has no
atmosphere to regulate temperature it has a very large temperature fluctuation.
Of all the planets in our solar system (apart from Earth), Mars is the one most likely to be hospitable to
life. In 1986, NASA found what they thought may be fossils of microscopic living things in a rock recovered
from Mars.
The sheer size of space makes it impossible to accurately predict just how many stars we have. Right
now, scientists and astronomers use the number of stars only within our galaxy, The Milky Way, to
estimate. That number is between 200-400 billion stars and there are estimated to be billions of galaxies
so the stars in space really are completely uncountable.
Discovered in 1705 by Edmond Halley, the famous comet was last seen in 1986 and is only seen once
every 75 to 76 years.
While the entire suit costs a cool $12m, 70% of that cost is for the backpack and control module.
As space facts go, this is pretty impressive. Research by Yale University scientists suggests that a rocky
planet called 55 Cancri e — which has a radius twice Earth’s, and a mass eight times greater – may have
a surface made up of graphite and diamond. It’s 40 light years away but visible to the naked eye in the
constellation of Cancer.
9. THE FOOTPRINTS ON THE MOON WILL BE THERE FOR 100 MILLION YEARS.
The Moon has no atmosphere, which means there is no wind to erode the surface and no water to wash
the footprints away. This means the footprints of the Apollo astronauts, along with spacecraft prints, rover-
prints and discarded material, will be there for millions of years.
Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around
the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.
11. IN 3.75 BILLION YEARS THE MILKY WAY AND ANDROMEDA GALAXIES WILL
COLLIDE.
The Andromeda Galaxy is approaching the Milky Way – where our solar system is – at rate of around
110 kilometres per second (68 mi/s) and eventually the two will collide to form a giant elliptical galaxy.
12. IF TWO PIECES OF THE SAME TYPE OF METAL TOUCH IN SPACE THEY WILL
PERMANENTLY BOND.
This incredible fact is also known as cold welding and it happens because the atoms of two pieces of
metal have no way of knowing they are separate. This doesn’t happen on Earth because of the air and
water found between the pieces.
Astronomers have found a massive water vapor cloud which holds 140 trillion times the mass of water in
the Earth’s oceans somewhere around 10 billion light years away – making it the largest discovery of
water ever found.
Discovered by Italian astronomer Giuseppe Piazzi in 1801, the dwarf planet Ceres was the first, and
largest, object to be considered an asteroid. It is located in the Asteroid Belt between the orbits
of Mars and Jupiter and accounts for 33% of the entire belt’s mass.
The theory is that when Earth was a relatively young planet, it was struck by a giant object and this
collision broke a piece of the Earth away to create the moon. This piece then began to orbit the Earth as
a result of its gravitational pull.
At 600 km wide and 21 km high, Olympus Mons is a volcano on Mars that may still be active, according to
scientists. It is the tallest peak of any planet. However, the Rheasilvia central peak on the asteroid Vesta
is taller at 22 km.
