Why do some planets not have life on them?

Answer 1

There are a couple of reasons. First, the gas giant planets are much larger, and therefore have much higher gravity. They CAN hold on to their atmosphere.

Secondly, Mercury is very close to the Sun, and the radiance of the Sun and the volume of the "solar wind" from up close there has blown whatever atmosphere Mercury MAY have had off into space. The gas giant planets are much further away, and the power of the Sun is correspondingly much less. Imagine standing right in front of a fan - and then moving back several feet. You'll feel the difference.

Answer 2

The whole idea of a black dwarf is that it no longer emits energy. A black dwarf is the final stage of a white dwarf, after it cooled down to the temperature of the environment, which at that time will be a fraction of a kelvin. Black dwarves don't currently exist; the Universe is too young for that, and white dwarves didn't have the time to cool down that much.

Answer 3

Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune are all uninhabitable.

Mercury is too hot. Venus is also too hot. Jupiter has too much atmospheric pressure, along with Saturn, Uranus, and Neptune. Anything farther than Mars is too cold, and Anything closer than Earth is too hot.

Answer 4

In OUR solar system, seven out of the eight planets have no life on them. You

should really be asking, "How is it possible for living life to live on a planet ?"

and "What does it take ?"

Answer 5

Some planets do not have life because they may lack essential conditions for life to exist, such as a suitable atmosphere, water, or temperature. Other factors like high levels of radiation or extreme conditions, such as high pressure or temperature, can also make a planet uninhabitable.

Answer 6

Because the gas giants have huge gravitational force compared to the one on mercury

Answer 7

There are no solid landmasses on any of the gas giants. Unless life was able to develop on the rocky core and was able to survive the huge pressure and temperature, no life can survive there.

Answer 8

Most likely for the same reason that the atmosphere of Earth doesn't

escape into space ... on account of the thing called 'gravity'.

Answer 9

All except Earth are impossible, and it's not that easy on Earth.
