The solar year of Venus should be shorter than the solar year of Mars because Venus is closer to the sun, so its rotation around the sun should take less time than a full rotation of the Sun for Mars. Also a solar year for Venus is 224.7 Earth days and a solar year for Mars is about 687 Earth days.
The length of one day on Venus is the same as 243 Earth days. This is because Venus rotates backwards compared to the other planets in the solar system. A day on Venus is actually longer than a year on Venus.
Mercury and Venus.
That's Mercury: "sidereal day" is more than half its year. Or, it could be Venus: "solar day" is just over half its year.
Venus is in the same solar system that we are.
No planet in our Solar System has 248 days in a year.The closest are:-Venus 224 days - although Venus has a day which lasts 243 days.Earth 365 days
This may be a vague reference to the fact that there are roughly 2 of Venus's "solar days" in one Venus year.
A Venus day (spin) is 1.08 times as long as a Venus year.The very slow rotational day of Venus is 243 Earth days long, while its year (one orbit of the Sun) is only about 225 Earth days. Combined with the retrograde direction of its spin, this produces a "solar day" (sunrise to sunrise) of about 116.75 Earth days.So in terms of rotation, there is only 0.925 days in a Venus year. In terms of daylight experienced on the surface, there are 1.92 Venus days per Venus year.
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.
One year on Venus is about 224 Earth days.
The rotational period of Venus is not the same as its solar day. It takes about 243 Earth days for Venus to make one slow spin, and it is in the opposite (retrograde) direction from its orbit. It can be said to spin clockwise, or east to west.At the same time, it takes only 224.7 Earth days for Venus to orbit the Sun (its year). So the "day" on Venus is actually longer than the year!(1 Venus year = 0.925 Venus sidereal day)HoweverThe result of these two motions produces a "solar day" (sunrise to sunrise) of about 116.75 Earth days on the planet, although obviously the sunrise cannot be seen from the surface.(1 Venus year = 1.92 solar days)
It's Mercury or Venus depending on whichthe definition of "day "you mean.
