Venus.
Edit: There seems to be a mistake in this question. There is no such planet.
But Venus does rotate on its axis in about 243 Earth days. So I guess
that the question is about Venus. The orbital period of Venus (a year)
is about 225 Earth days.
Mercury is the planet with an 88-day year.
There is a planet not of our solar system that orbits it's sun within four of our days. So a year for that plant is only four days here on earth.
Venus. The rotational (day) period is243.2 earth days, and the sidereal (year) period is 224.7 earth days, the only planet in our solar system that has a year that is shorter than a day.
Mercury. Mercury takes 88 days to go around the sun, so its year is 88 solar days.
Earth is the only planet which is known to harbour life.
Mercury, the closest planet to the sun, has an orbital period (year) equal to 88 Earth days.
Mercury, the closest planet to the sun, has an orbital period (year) equal to 88 Earth days.
Mercury is the planet with an 88-day year.
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.
Mercury has the shortest year of any of the planets. It is only 88 days. Mercury's day takes 58.646 Earth days.
Mercury
The Earth rotates in about 23 hours and 56 minutes. That's called the "sidereal day". The sidereal day on Venus is about 243 Earth days. As a year on Venus is only about 224.7 Earth days, this makes Venus' day longer than its year. Venus is the only planet in our Solar System to have this feature.
Because Mercury orbits the Sun much faster than Earth. It takes Earth 365 days to orbit the sun once, but it only takes Mercury 88 days.
The earth is the only planet on earth.
Venus does, roughly speaking. Its year is 224.7 Earth days. It has a "solar day " of about 116.75 Earth days.
If man developed on this planet first and only, then the Earth or Tellus is the only planet inhabited by man. It might be disputed if our planet is the first one or the only one. Science does not know for certain but the odds with to days knowledge are against theories of man coming to earth from other planets.
Venus. Its day is -243.0185 Earth days long. The "minus" means it rotates in the direction opposite to the Earth and all the other planets (except Uranus). Another viewpoint: That's the time to spin once, called the "sidereal day". The "solar day" is defined in a different way and is only about 116.75 Earth days long for Venus. On that definition, it is Mercury that has the longest day (about 176 Earth days.)
