Each sidereal day on Mercury takes 58.65 Earth days.
It was once thought that Mercury always kept one
side toward the Sun, but that turns out not to be true.
The time from sunrise to sunrise is 176 Earth days.

Actually, Mercury takes 58 DAYS to turn once on its axis. That said, because its rotation rate is 2/3's of its revolution period, it creates a much longer "day" for someone standing on the surface. In fact, for an observer on the surface, it is 176 days from one sunrise to the next. The sun also exhibits cycles of retrograde motion on Mercury. That means it is sometimes possible for the sun to rise, change direction and set in the same place, only to change direction and rise again. (Note, it doesn't do that every sunrise...just when the cycles line up that way.)
Wow....maxhedr00m is quoting data that was disproven over 30 years ago. Amazing.

Its orbit (around the sun) is 88 days (takes 1 year for Earth)
Its rotation (around its axis) 59 days (takes 1 day on Earth)

There is no day or night on mercury. The planet does not rotate so one side constantly faces the sun.
