Mercury actually does have an atmosphere but the planet's small size makes it hard to retain. It is not stable.

YES, BUT...
A thin but strong wind from the Sun blasts particles off of Mercury's hard surface, creating a thin atmosphere around the planet.

So far, observations of Mercury from ground-based observers and the Mariner 10 spacecraft have not shown evidence of a significant atmosphere compared to other planets.

Not really, it's too small to be able to hold any real atmosphere although it does have a very thin gas envelope formed from particles captured from the sun

Yes buit it is so thin that it is not classified as an atmosphere.

yes. but very little. we won't survive if we ever do try to colonize there. mars, we might survive for a minute.
