Which planet has a year that is only 243 Earth days long?
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, 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.
Planet Mercury because it is only 88 earth days
They are about 88 Earth days each. The "solar day" is about 176 Earth days. Mercury only has a small axial tilt. So, night and day should be about equal in length everywhere on the planet.
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.
the planet is venus. a day on venus is equal to 243 Earth days but a year on venus is only equal to 224 or 225 Earth days.
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.
One day on Venus is equivalent to approximately 243 Earth days. Venus is the only planet in our solar system to rotate clockwise, and the length of its day is longer than the length of its year - 224.7 Earth days.
Saturn's year lasts 29.5 Earth years, however Saturn's day lasts only 10.6 Earth Hours. That is less than half of one Earth day.
Mercury completes an orbit of the Sun in 88 Earth days, which is about 3 months or 0.24 Earth years. The slowly spinning planet makes only 1.5 rotations per revolution, giving a sidereal day of 58.6 Earth days but a solar day, sunrise to sunrise, of 176 Earth days (twice as long as its year).
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 does, roughly speaking. Its year is 224.7 Earth days. It has a "solar day " of about 116.75 Earth days.
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.)
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.
What is the difference between the period of rotation of a planet and the orbital period of a planet around the sun?
period of rotation = day (24 hrs. only for Earth) orbital period = year (not 365.25 days only for Earth)
The Planet Mercury has the shortest year. A year on Mercury takes only 88 Earth days.
Planet earth is the only planet that we know of that has life on it.
The planet Earth is a terrestrial planet and the only planet known that has life on it.
earth cant be the only planet because if earth was full there can anyone to live on it
Yes,because earth is the only planet with oxygen and the planet that can supports life
Earth is the only planet known to have life and liquid water.
Earth is a are home planet ,and the only planet that contains life
It can take up to 58 Earth days, 15 Earth hours, for a single rotation of the planet. A year is only around 88 Earth Days though.
Venus. The day is 243 earth days long and the year is only 225. Mercury is another weird case. Its year is about 88 earth days long. Its sidereal day is 2/3 of that, 58 2/3 earth days. So in effect it would seem that the daytime lasts a year and the nighttime lasts a year.
No. Nature exists on and in every planet. Earth is, however, the only planet in our solar system to have life.
Mercury. Mercury takes 88 days to go around the sun, so its year is 88 solar days.
I think you are refering to the planet Nibiru. The planet only exists in science fiction and internet hoaxes.
Mercury is the planet that has the shortest year. This is because it is the nearest planet to the sun. It only takes 88 Earth days for Mercury to complete one orbit.
planet earth is known for being the only planet to support life
it depends what planet your on Mars: open 7 days a week jUPITOR: only 6 days a week; not on sunday....very religious planet earth: not open on sundays
Our planet, the Earth is the only planet with drinkable water. It is the only planet in our Solar System with life and oxygen. Without the oxygen, there will be no life and water on Earth.
The planet Neptune is farther from the Sun and has a much longer orbit than Earth's. It takes 164.79 Earth years for Neptune to complete its orbit. Because the "day" on Neptune is only about 16 Earth hours long, the year on Neptune, while equal to 60,190 Earth days, is about 89,666 "Neptune days".
Mercury's year is only 87.9 Earth days long.
The gravity of the Sun has slowed the rotation of Mercury, so it takes almost 59 Earth days to spin once on its axis (58.646 days). At the same time, the relatively brief orbital period (Mercury year) is only 88 days long, even further reducing the apparent motion of the Sun as seen from the planet. A "solar day" (sunrise to sunrise) on Mercury lasts 176 Earth days, or twice as long as its year!
The earth is special in that it is the only known planet to have life on it.
Earth is the only planet currently known to have life.
The planet that takes the least amount of time to make an orbit of the sun is mercury, the closest planet. It takes only 88 days to make one orbit so has a 'year' of 88 days.
Venus, it takes 243 earth days for each rotation while it's planetary orbit takes only 225 earth days.
beause earth is the only planet which has oxygen and other needed sudstances .
Well considering that Earth is the only planet we mine. The answer has to be yes.
243 earth days. 0.615earth years. That's the time of one rotation, called the sidereal day. There is another "day" called the solar day.This is about 117 Earth days. The solar day depends not only on the rotation of a planet,but also on it's movement around the Sun in its orbit. On Earth we hardly notice the difference between our two "days" as they only differ by about 4 minutes.
Jupiter makes a complete rotation in only 9.9 earth hours and has the shortest day of any planet. This is because the planet spins very quickly.
Earth is the only planet with life.
only earth is a living planet.
Because Earth is the only planet with oxygen, water and food. And living creatures need these things to survive. We would die in 3 seconds if we don't have air; 3 days if there is no water; and 3 weeks if there is no food.
Our planet, earth, is the only planet that has evidence of life on it.
The length of a year (orbit) for Mercury is 88 Earth days, about 1/4 that of Earth. The planet spins 1.5 times during that period, about once every 58.7 Earth days. The combination of these motions results in a "solar day" (sunrise to sunrise) of 176 Earth days, or exactly twice as long as the year. So you could say that a Mercury year is only half of a Mercury solar day.
