Mars.
The planet Mars has a very thin atmosphere, similar to the moon.
Mercury's atmosphere is so thin that it is barely detectable.
Mars has a thin, mainly carbon dioxide atmosphere.
Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.
Hard to say, as the distance from the star will also factor in, but in general, thin atmosphere would mean no insulation, it would be cold. Mars is a classic example of a planet having a thin atmosphere. It is extremely cold on Mars and has a small amount of carbon dioxide in it's atmosphere but is not in high enough concentration to warm the planet. Mercury has no atmosphere and it is hot and cold depending on which part of the planet is facing the Sun. Venus has a very dense amosphere and it is very hot, no matter which surface is facing the Sun.
The terrestrial planet that has no atmosphere is Mercury. Its thin atmosphere consists mainly of trace amounts of oxygen, sodium, hydrogen, helium, and potassium, and is not enough to be considered a true atmosphere.
