Mars. It has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
Venus has almost the same mass as Earth.
Earth.
Venus because it is almost the same size as Earth.
it is mars it has water
Here's some ideas : Its day length is almost the same as Earth's. Its axial tilt is almost the same as Earth's. It has volcanoes. It has polar ice caps.
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.
Venus, it is slightly smaller, and much hotter
it's almost the same ... but earth's is a little bit more
I assume you mean "planet". That would be Venus.
no planet
