What characteristics does earth have that other planets don't?

Answer 1

There are numerous characteristics that the Earth has but other planets do not. Some of them are

Life: The most important characteristic that the Earth possesses and other planets do not is "life". So far, its the only planet discovered by mankind to have life. Although some ufologists (people who study about life in other planets) claim that life is present in other parts of the universe, these are only hypothetical views.

Liquid Water: Liquid water till yet has been discovered only on Earth and no other planet. Although certain planets like Mars has polar zones covered with ice, yet the probability of liquid water is very less. The ice actually has never melted for years.

Atmospheric Composition: The atmospheric composition and atmospheric pressure is a major point to be noted here. The atmospheric composition of Earth with 79% Nitrogen, 21% Oxygen and very little carbon dioxide (0.04%) is just the perfect ratio for sustainance of life. Planets like Jupiter has most of the atmosphere composed of methane, hydrogen and ammonia. Other bodies like the Moon (not a planet) has no atmosphere at all because of low gravity.

There are other factors like gravity, size, colour (the Earth appears blue from space), etc are also there which differentiate it from other planets.

Answer 2

Earth is the only planet known to have liquid water on its surface, a diverse range of life forms, and a breathable atmosphere containing abundant oxygen. It also has a relatively stable climate and protective magnetic field, making it unique among the planets in our solar system.

Answer 3

The planet Earth is at a distance from the sun which permits water to exist in all 3 phases, solid, liquid, and gas. Other planets in our solar system are either too close to, or too far from the sun for liquid water. The Earth is also notable for having a satellite, the moon, which is closer in size to the planet that it orbits (the Earth) than any other satellite in our system is to the planet that it orbits (that is to say, while there are other large satellites in the solar system, even the largest is relatively small compared to the planets which they orbit; only the Earth-moon combination is close to being a double planet). And of course, the Earth is notable for having life. No life has been found elsewhere in the solar system. Other stars may have planets which resemble the Earth, but we have not had the opportunity to examine them.

Answer 4

Earth Isnt too hot or too cold. It is positioned perfectly near the sun. It has water and Oxygen. No living things can live without that. It Has life and no other planet does (that we know of).

Answer 5

It has life, has a breathable atmosphere and a surface temperature around the 'triple point' of water.

Answer 6

It contains Life.

It also contains water in liquid form.

Answer 7

presence of oxygen..... presence of water............. presence of life................

Answer 8

Liquid surface water

Answer 9

i like vaginas

Answer 10

as far as i know an atmosphere
