Mercury is reminiscent of the Moon - simply a ball of rock hotter than our satellite. Despite its appearance, though, the planet actually does have an atmosphere. Some astronomers believe that Mercury originally had a thick atmosphere like Earth, but the planet is so small that it has very low gravity. As a result of the planet's low gravity, Mercury's atmosphere was blown away by strong solar winds. This barely existent atmosphere is made of a number of compounds including hydrogen, oxygen, water vapor, and potassium.
You can only survive on Earth but no other planet.
The earth orbits the sun between the planets Venus and Mars. The other five planets are farther out than Mars. The closest earth gets to Venus is 23.7 million miles. The closest earth gets to Mars is 36.4 million miles.
Compared to some other planets in the same galaxy, yes; it is actually fractions of the size of other planets in this galaxy
This is because there is absolutely no trees on other planets.Mean while the trees are the propagators of oxygen on earth.hence the absence of oxygen on other planets.
earth is the only planet known to house liquid water and life
No, they are usually have thicker lithospheres.
The lithosphere is the solid, outer part of a planet. All terrestrial planets have lithospheres, but the lithospheres found on Mercury, Venus, and Mars, are thicker and more rigid than Earth's. Mercury's lithosphere lacks fluids and is thick and immobile. It has not changed much in the last billion years.
The other planets do have gravity.
No. Earth's magnetic field only affects earth, not other planets.
Since no one from Earth has visited another planet, and we have no indication that there is anyone on the other planets, Earth does not help other planets in any way. Why do you think there is something Earth does to help them- whoever them is.
yes, the earth and other planets revolve around the sun
Earth and the other planets are mostly made of rock.
Earth and the other planets are mostly made of rock.
The other planets actually do have seasons.
Earth contains a lithosphere that contains the crust and the mantle. There are two types of lithospheres on earth which are the oceanic and the continental.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
