Mars has a day slightly over 39 minutes longer than Earth's.
mars
venus does because it rotates as earth does and it is earths twin baby
I`ll assume by a day you mean an Earth day (24 hours). Saturn rather !
It should be --- Earth Day, Planet Earth.
This is planet Earth, so one Earth day is one day on this planet.
Mars. It has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
The planet Mercury has a day that is almost the same length as its year. Mercury's rotation period is about 59 Earth days, which is very close to its orbital period around the Sun of about 88 Earth days. This means that one day on Mercury is almost as long as one year on Mercury.
Mars is pretty close, at about 24 hours and 37 minutes.
A day on Saturn is about 11 hours on Earth.
Earth is the only planet with a day of 23.9 hours.
It's Mars.
