murcury
The "Solar day" on Venus. Or, the "Sidereal day" on Mercury.
That's Mercury: "sidereal day" is more than half its year. Or, it could be Venus: "solar day" is just over half its year.
murcury
Venus or Mercury, depending on the definition of "day" used. It takes Venus 243 Earth days to spin on its axis relative to the background stars (a "sidereal day"). It takes Venus 224.7 Earth days to orbit the Sun (its year). However, a "solar day" is only 116.75 Earth days long due to the combination of rotation time, orbit time and spin direction. (Venus spins in the other direction to Earth and most other planets.)Mercury has a "sidereal day" of about 58.6 Earth days and a year of about 88 Earth days.
Inside the arctic circle, it can be "day" all day long, all 24 hours long. At the poles, this will continue for half a year. The other half year is night.
YEAR
Around a year or so or about a day or half a day or 365 and a half days :D
Mercury's day is about 58.65 Earth days, and its year about 87.97. Venus has a day that is 243.0 Earth days long, while its year is only 224.7.
