Which planet is hottest and why?

Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet. The mean temperatures of planets in our solar system are: Mercury – 333°F (167°C) Venus – 867°F (464°C)

Why is Venus always so hot?

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

Why is Mercury hotter than Venus?

The fact that Venus is hotter than Mercury has to do with the atmospheres of the two planets. Venus has a rather dense atmosphere; Mercury has almost no atmosphere. Mercury’s absence of a significant atmosphere means the planet has almost no capacity to trap and hold heat from sunlight.

There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause water to immediately boil away.

What Colour is Venus?

Which 2 planets are known as ice giants?

The “ice giants” Uranus and Neptune are made primarily of heavier stuff, probably the next most abundant elements in the Sun – oxygen, carbon, nitrogen, and sulfur. For each giant planet the core is the “seed” around which it accreted nebular gas. The ice giants may be more seed than gas.
