Because they are just for aliens. Aliens don't have to breathe, but we do.
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
Superior planets (those outside Earth's orbit) appear brightest when they are at opposition, which is when they are on the opposite side of Earth from the Sun. This is when they are closest to Earth and fully illuminated by the Sun.
In the course of their orbital revolutions, the planets Mercury, Venus, and Mars can be closer to the earth than the sun is. All of the other planets in the solar system are always farther from earth than the sun is. All other stars are much, much, much farther from earth than the sun or any of the planets in our solar system.
The other planet's are too hot or too cold and don't have an atmosphere, therefore killing everything.
i dont realy know
yes there are seasons like earth on other planets. Except, they all dont have the same tempuratures or the same period one or more season lasts.
Probes are used to get samples and to also see what there is on other planets

I dont know but i think something will crush youre brains and kill you
i dont know you guys find the answer. lazy retards!!!!
Astronomers study celestial objects such as stars, planets, and galaxies, which are located in space above Earth. While astronomers may not focus on the geology or atmosphere of Earth, their work is still aligned with studying the natural phenomena of the universe, making them closely related to Earth scientists.
the sun is a very large gasious fire ball,if the gases dont move the sun will exploade and burn earth and some other planets to a crisp.:)
