The lack of an atmosphere, on any planet, will stop greenhouse gasses from building up, so the heat won't be trapped causing a cooler climate.

Why are the temperatures on venus and Murcury so different?
The main difference is that Venus has a dense atmosphere, while Mercury has none. The usually accepted theory is that something in Venus' atmosphere caused a runaway greenhouse effect.
Which planet has the thickest atmosphere?
Venus has the thickest atmosphere is our solar system
Which planet has the hottest surface temperature?
Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus is the hottestas the thick Carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
Which planet has the heaviest atmosphere?
all planets have atmospheres. However, Mercury has extremely low atmospheric pressure, Mars has an atmosphere way below the Armstrong Limit, and Venus and the Outer worlds have way too high of an atmosphere.
Why does venus have higher surface temperatures than mercury even though venus is farther from the sun?
Because Venus is closer to the sun than Earth is, it receives more solar energy than Earth does. Much of this radiation is reflected by Venus's clouds, but some radiation reaches the surface and is later given off as heat. The carbon dioxide in Venus's atmosphere traps heat so well that Venus has the hottest surface among the planets. This trapping of heat by the atmosphere is called the greenhouse effect.
Distinguish planet Venus from Mercury?
Mercury is much closer to the sun than Venus. It has less of an atmosphere, much higher temperatures, and a very short year. Venus has an very sulfur-rich atmosphere, cooler temperatures than Mercury, and a longer year than Mercury.
Do Mercury and Venus have thick atmospheres?
Venus has a thick atmosphere. Mercury does not have an atmosphere.
Why are the temperatures on venus and Murcury so different?
The main difference is that Venus has a dense atmosphere, while Mercury has none. The usually accepted theory is that something in Venus' atmosphere caused a runaway greenhouse effect.
Why is Venus the planet that has the highest temperature?
Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere. Surface temperatures on Venus average 735 Kelvin or 460 °C.
Why are the temperatures on each of the others terrestrial planets more extreme than the temperatures on earth?
On Mercury & Mars there is negligible atmosphere thus extremes in temperature.On Venus its hot - constantly. Because the atmosphere is much thicker.
Which planets have the warmest temperatures?
The inner, rockey or terrestrial planets (Mercury, Venus, Earth and Mars). these are warm as they are closer to the sun than the gas giants. Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
What planet has the warmest surface temperatures?
Venus because it has an atmosphere and is closer to the Sun than the Earth. It keeps in more heat than Mercury
Why is venus more hoter than Mercury?
Venus is hotter than Mercury because Venus has a atmosphere and Mercury doesn't so Mercury can't keep so much heat in as Venus can.
Why does Venus have higher surface temperature than mercury even though Venus is farther from the sun?
Thick atmosphere on Venus none on Mercury
Is Mercury the hottest planet in space?
Surface temperatures place Venus above Mercury.
How is Venus hotter than mercury because Mercury is closer to the sun than Venus?
Venus is hotter than Mercury because Venus traps heat and cannot escape from the Sun in the atmosphere.
Which planet has no atmosphere and no moons?
Mercury has no moons and no atmosphere. Venus has an atmosphere but no moons. Mercury probably has no moons and no atmosphere because it is very close to the sun.
