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.
Mercury does not have enough gravity to hold this?
ya it has a little bit less gravity than the moon. its........floaty..........
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.
Which planets have no atmosphere?
Mercury and the Moon have very thin atmospheres that are considered more like exospheres than traditional atmospheres. However, the gas density is so low that they are often considered to have no significant atmosphere.
What moon or planet doesn't have enough gravity to have an atmosphere?
-- Mercury -- moon of Earth -- moons of Mars -- majority of moons of Jupiter and Saturn Note: While Mars technically has an atmosphere, its density is only around 1% of the density of earth's atmosphere, so Mars is very close to joining the list.
What is the atmosphere on Mercury is due to?
The extremely thin atmosphere on Mercury is due to the planet's relatively low gravity, which is not strong enough to hold on to gases. Any atmosphere that Mercury may have had in the past would have been stripped away by solar wind and radiation.
What is the Mercurys atmosphere compared to earth?
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
Which planet does not have enough gravity to have an atmosphere?
Nercury
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.
