Why doesnt mercury have an atmosphere?
One word- gravity. Mercury is just simply not massive enough to generate the gravity required to hold gases close enough to the surface to create an atmosphere.
Which planets have no atmosphere?
Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.
What planet doesn't have enough gravity to have an atmosphere?
Mercury - the closest planet to the sun. Solar wind and radiation from the sun also blast off some of Mercury's minuscule atmosphere (Mercury's atmosphere is sometimes referred to as an exosphere)

What holds the Earth's atmosphere in place?
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
Why doesn't mercury get sucked in the suns gravity?
That is impossible because the perimeter of the sun is where the gravity is. And the atmosphere is not where the gravity is.
What holds the atmosphere to the earth?
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
Which planet does not have enough gravity to have an atmosphere?
Nercury
If mercury wasn't so close to the sun could it hold an atmosphere Or is it too small?
It's a combination of both. Despite its weak gravity, there would probably be a point, far enough from the Sun, where an atmosphere would be cold enough so that it didn't "evaporate" into space too quickly. But I am not sure how far that would be.
Does mercury have enough ability to support life?
No because mercury has a thin atmosphere
Would a can be crushed due to gravity or atmospheric pressure on mercury?
No, because Mercury has practically no atmosphere and only a little more than a third the gravity of earth.
