There are a lot of different kinds of aliens, and the ones we know about tend to be pretty alien.
They may not look human or be human, but they have been found to be much bigger, more advanced than we can even imagine.
They’re known as the “snow mountains” because of their snow-covered terrain.
And a lot are more advanced.
Here are five of the biggest, most fascinating, and most scientifically challenging.
1.
Mars The Red Planet has been visited by at least one extraterrestrial being in its history, which is pretty awesome, if you ask us.
But we’re not sure if that’s really a thing.
Mars was discovered by NASA in 1972.
It was believed that it was the home of life, and scientists thought that it might be habitable.
But as the decade of the 1970s came to an end, the planet became a bit more interesting to us.
Scientists were able to measure water in the Martian atmosphere, and then were able get to see how water changed over time.
They also found traces of methane on the surface, and were able see traces of oxygen on the Martian surface.
Scientists believe that Mars is the most habitable planet in the solar system, and that it is probably the most Earth-like planet we’ve ever seen.
2.
Jupiter There are at least a couple of planets that orbit our star, and we know that some of them are very different from the rest.
Jupiter is one of them.
It is a gas giant that orbits the Sun in its own gravity.
The atmosphere of Jupiter is dense, with the outer layers of its surface being ice.
The planet is covered in clouds, with some of the planet’s largest, most intense clouds being found at the poles.
Jupiter’s atmosphere is so thick that some researchers believe that the gas giant could support a super-Earth, a world that is more massive than Earth and is not habitable.
3.
Neptune Neptune’s largest moon, Triton, is one half of the largest moon in the Solar System.
Its gravity is strong enough to make Tritons surface dark and ice-covered, but it is not as massive as Jupiter or Saturn.
The moon is so massive that scientists believe it is able to hold an atmosphere that is comparable to that of Earth.
This is because Neptune is so close to the Sun that the Sun’s light is directly reflected off of its atmosphere.
In addition, the Sun has enough energy to make the planet orbit around the Sun, and it is in the same orbit around Earth as Saturn.
Neptune is thought to be the most distant moon from Earth, and so far scientists have only seen its moon in infrared light.
4.
Uranus Uranus is the ninth largest planet in our solar system.
It orbits in a relatively close orbit with the Sun.
Uranuses surface is ice-rich and has thick, rocky layers.
It has also been found that the atmosphere of Uranus can be a bit chilly, which can make it look like a frigid planet.
Uranis surface is not very rocky, and its ice-filled surface can be covered in the occasional cloud.
However, it is said that the icy crust of Uranis has an average thickness of more than 200 miles (322 kilometers).
5.
Jupiter Jupiter is also a gas planet.
It doesn’t have an atmosphere and is quite hot.
However it has also found that its atmosphere is able not only to reflect some of Earth’s light, but to create a very hot surface.
This can make for some spectacular views.
For example, Jupiter has two moons: Io and Europa.
Io and Jupiter have the largest moons in the known solar system at roughly 4,000 and 1,400 kilometers (2,300 and 1.5 miles), respectively.
They orbit the Sun at an average distance of 6.6 million miles (11.8 million kilometers), which is about half the distance from Earth to the Moon.
