Is Earth a star?
The Earth is an example of a planet and orbits the sun
, which is a star. A star is usually defined as a body of gas which is large enough and dense enough that the heat and crushing pressure at its center produces nuclear fusion. This is a fancy way of saying that it glows or burns, like our sun.

.
What is the hottest planet?
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Why is Venus the hottest planet?
Venus is so
hot because it is surrounded by a very thick atmosphere
which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. … The heat becomes trapped and builds up to extremely high temperatures.
Is Sun a planet?

Can humans live on Mercury?
Mercury is not a planet that would be easy to survive on but
it may not be impossible
. It is worth noting that without a space suit you would not survive very long at all, due to a lack of atmosphere. On top of this Mercury has one of the largest changes in temperature in the Solar System.
What is the 7 planet?
