Is it true that a day on Venus is longer than its year?
Yes. Venus takes 243 Earth days to rotate once, but only 225 days to orbit the Sun, so its day is longer than its year.
It also spins in the opposite direction to most planets, which means the Sun rises in the west there.
How hot does it get on the surface?
The surface sits around 465°C, hot enough to melt lead. The atmosphere traps so much heat that Venus stays hotter than Mercury, even though Mercury is much closer to the Sun.
