The sidereal day is about 243 Earth days. That is the time for the planet to
rotate once .
The solar day is 117 Earth days,roughly. That is a big difference. On Earth
the difference between these two days is only about 4 minutes.
The reason for the big difference on Venus is that Venus rotates very slowly.
The solar day depends on the rotation of a planet AND its orbital motion.
The slow rotation makes the effect of the orbital motion much greater on
the length of the solar day.
Incidentally Venus rotates in the opposite direction to Earth. That's why
the solar day is shorter than the sidereal day. On Earth it's the other
way round.
What else can I help you with?
How many days long is Venus' years?
Solar day (24 hours for the Earth): about 116.75 Earth days. Sidereal day (rotation period, about 23 hours and 56 minutes for the Earth): about 243 Earth days. Year: about 224.7 Earth days.
What planets days are longer than your year?
Venus "sidereal day" is longer than its year. Mercury's "solar day" is longer than its year. However, there is no planet in our solar system with a day longer than our year on Earth.
What planet in your solar system has the longest day?
Venus, its day is equivalent to 243 Earth Days. That's the rotation period, or "sidereal day". However the "solar day" on Venus is only about 117 Earth days. If you mean the "solar day" then Mercury has the longest day because Mercury has a solar day of about 176 Earth days.
Which planets day is more than half as long as its year?
It's Mercury or Venus depending on whichthe definition of "day "you mean.
What is the name of the planet with the longest day compared to an earth day?
Venus. The length of "day" is 243 Earth days. That's the rotation period which is called a "sidereal day". However, there's also a "day" called the "solar day". That's the time for the Sun to complete one apparent journey around the sky. For that definition of "day", it is Mercury that has the longest day at about 176 Earth days.
What is the length of day of the planet Venus?
It is about 117 Earth days (for the "solar day") or 243 Earth days (for the "sidereal day").
Length of Venus day?
243 days on earth
How long its day?
243 Earth days is the rotation period of Venus. That's its "sidereal day" length. The other main definition of a "day" is called a "solar day". For Venus that's only about 117 Earth days in length.
What is the length of the day on the planet with the highest average surface temperature?
That planet is Venus. The rotation period of Venus is 243 Earth days. That's called a "sidereal day". On Earth the sidereal day is about 23 hours and 56 minutes. There is also the "solar day", based on the position of the Sun in the sky. On Earth, that's exactly 24 hours. On Venus the solar day is about 117 Earth days in length. As you can see, there is a huge difference in the lengths of the two days on Venus. That's because Venus rotates very slowly.
What planet has the greatest similarity between the length of its day and the length of its year?
Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.
What are some major characteristics of Venus?
Venus has 95 percent carbon dioxide in it's atmospheric composition therefore it has the strongest green house effect in the whole solar system. Venus shows Retrograde rotation. A sidereal year on Venus is shorter than a sidereal day on Venus. Venus's rotation is slowest in the whole solar system.
How many earth days equal one sidereal day on venus?
The sidereal day is the time it takes for a planet to rotate once. For Venus that's about 243 of our Earth days.
The length of one day in Venus or even a year?
It takes Venus about 243 Earth days to complete one rotation on its axis, making a day on Venus longer than a year on Venus (225 Earth days). This means that a day on Venus is longer than a year on Venus.
Which is longer the stellar day the sidereal day or the solar day?
Usually the solar day is the longest. The other two are very similar in length to each other. For example, the solar day on Earth is about 4 minutes longer than the other two "days". However, for the planet Venus the solar day is the shortest. That's because Venus has retrograde rotation.
What planets days is more than half as long as its years?
The "Solar day" on Venus. Or, the "Sidereal day" on Mercury.
How long is one day rotation on venus?
Instead of a similar rotational period to Earth's 24 hours, Venus takes 243 Earth days to rotate once. That's called a "sidereal day". In other words, a "day" on Venus is longer than its "year". This is the longest day in the entire Solar System. (Don't forget the "solar day" though. That's only about 117 Earth days on Venus.)
How long are the days on Venus compared to the days on Earth?
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.
