As time goes by, technological advancements have seen us learn more facts about space in the past century than in all time before that. Here are some space facts to keep your day going.
There are 176 confirmed moons in our solar system, with some of them being bigger than Mercury itself
* The hottest planet in our solar system is Venus
Most people thinking that this would be Mercury, as it is the closest planet to the Sun. However, Venus has a lot of gases in it's atmosphere which creates a greenhouse effect that causes a constant temperature of 864 degrees everywhere on the planet's surface
It's peak is (25km) high, making it nearly 3 times higher than mount Everest
* Pluto is smaller than the United States
If you were to walk around the equator of Pluto, it would be the same distance as walking from London to Denver
* Uranus blue glow is due to the gases in it's atmosphere
Uranus atmosphere is made up of hydrogen, helium and methane
* There are four planets in our solar system known as gas giants. Jupiter, Saturn, Uranus and Neptune
A gas giant is a large planet that is made up of mostly gases like hydrogen and helium Ang has a relatively small rocky core.
* We always see the same side of the moon, no matter where we stand on earth
This is because the moon rotates on its axis at the same rate that it rotates the earth. It is known as tidal locking.
* On Venus, it snows metal and rains sulphuric acid.
This is because Venus is a scorching planet choked with sulphuric acid, which causes the planet's metals to become gas and then liquid in the atmosphere, before raining down to the ground after the freezing temperature turn it into solid.
* Saturn is the only planet that could float on water.
Although Saturn is the second largest planet in our solar system, it is also the lightest. Saturn could float in water because it is mostly made of gas.
* A sunset on Mars is blue
Mars has less than 1percent of Earth's atmosphere, so the sunset on Mars appears as blue due to the way the blue light is captured within the atmosphere.
* There are 5 dwarf planets recognized in our solar system. Ceres, Makemake, Haumea, Eris and Pluto
* In 2016, scientist detected a radio signal from a source 5 billion light years away.
This means that when the signal started it's journey, earth didn't even exist.
