Why is there such a huge difference in temperature between the two sides of the planet mercury?
The main reason is that Mercury has almost no atmosphere which would hold the heat in. So the temperature on the side which is facing away from the Sun can plummet.
Is Mercury a gem?
No. Mercury is a metal that is liquid at room temperature. Melting point is  -38.83° C (ie a solid below this temperature) Boiling Point is 356.73 °C (ie a gas above this temperature) (All at 1 atmosphere pressure)
Does mercury have a heavy atmosphere or no atmosphere?
No atmosphere
Why are days on Mercury very hot and nights very cold?
Mercury has nearly no atmosphere. Without an atmosphere, Mercury cannot reflect sunlight or trap heat. This is the reason why days on Mercury are very hot and nights are very cold. In the daytime, the solar energy directly strikes the planet's surface because there is no atmosphere to reflect heat, making a sizzling temperature of 427 Celsius (800 Fahrenheit). At night, without an atmosphere to trap heat, the solar energy escapes quickly into space, resulting in a freezing temperature of -173 Celsius (-290 Fahrenheit).
Do Mercury and Venus have thick atmospheres?
Venus has a thick atmosphere. Mercury does not have an atmosphere.
Which planet has no atmosphere what is the consequence of this?
Mercury has not atmosphere, resulting in extreme temperature variations.
Can Mercury trap heat?
No, Mercury has no atmosphere. Without an Atmosphere planets cannot trap heat. This is the reason why Mercury's temperature changes drastically from day and night.
Which planet has no atmosphere and the day time temperature is 700K?
Mercury
Why are the temperature ranges on mercury so dramatic?
Because it doesn't have an atmosphere or its atmosphere is very thin
What planet has extreme temperature because it has no atmosphere?
Jupiter(: <----WRONG! It is Mercury.
Is Mercury suitable for life?
No, Mercury is not at all suitable for life. It has no atmosphere and no water, and has horrific temperature extremes.
Why was Mercury unable to retain an atmosphere during formations?
Mercury has a high surface temperature and a low mass
Why was mercury able to retain its atmosphere during its formation?
Mercury has a high surface temperature and a low mass
Would life survive on Mercury?
Not any life that we know of. Besides the obvious temperature problems, there is no atmosphere, and no water on Mercury.
What planet is the highest temperature is our solar system?
Planet with an atmosphere, Venus. Planet without an atmosphere, Mercury (on the day side).
Why does Mercury's temperature range from 400 degress celsius to 180 degrees celsius?
The planet Mercury is very close to the sun, but it has a very thin atmosphere. So, Mercury lacks an atmosphere in order to hold the Sun's heat.
What planet hat the hottiest temperature?
Venus. It is further away to the sun than Mercury, but Mercury has a thin atmosphere. Venus has a very thick, toxic atmosphere that traps all the sun's heat.
