Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
No. The planet Mercury does not have an atmosphere.
Mercury is the only major planet without an atmosphere. It is able to hold some gases close to its surface, but not really enough to call it an atmosphere. Its due to the size of the planet being so small and lack of a decent magnetic field that it is unable to sustain an atmosphere.
The lack of atmosphere on a planet can result in extreme temperature variations between day and night, as well as high levels of radiation from the sun. Without an atmosphere to trap heat, temperatures can drop drastically at night. Additionally, the absence of atmospheric pressure can make it difficult for liquid water to exist on the planet's surface.
The thinnest atmosphere belongs to planet Mercury . . . it may have no atmosphere, at all.
Every planet in the solar system except Mercury has an atmosphere, and all but Mars and Mercury have clouds, but only Earth has liquid water.
Water, atmosphere.
Water, and an atmosphere

No planet in our solar system has an atmosphere made largely of water vapor. There may be such planets orbiting other stars, but none have been conclusively found.
Earth is the only planet with a bountiful supply of water.

Because its atmosphere has a blue colour.
No. Mercury is a geologically dead planet. It has no volcanoes, not atmosphere, and no water.
what is the terrestrial planet that has no atmosphere
No. The planet Mercury does not have an atmosphere.
