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 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.
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.
What takes longer one year in venus or mercuty?
If you define a "year" for a planet as the length of time for it to make one revolution around the sun (the sidereal period) the "years" for the two planets are: Mercury 0.241 earth year (88.0 days) Venus 0.615 earth year (225 days) ... so Venus has a longer "year" than Mercury.
The length of one day in Venus or even a year?
Venus takes 243 days to spin on its axis relative to the background stars, while it takes 224.7 days to orbit the sun.Although its spin on its axis is longer that its orbital period, an apparent or solar day is 116.75 days, since it spins in the other direction to Earth and most other planets.The length of the solar day is about 117 days. Thus a Venusian year is less than 2 Venus days long!Good, an answer that mentions the solar day. Remember though thereis also the sidereal day which is about 243 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 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 is a day longer than year?
Venus: Venus has a "sidereal" day (rotation period)that's longer than its "year" (orbital period).A siderealday on Venus is equal to about243 Earth days, whereas a year is about 224.7 Earth days.Mercury:It takes Mercury about58.64 Earth days to spin on its axis - which is one Mercury siderealday. However, the "solar " day on Mercury is about 176 Earth days long.It takes Mercury about87.96 Earth days to orbit the Sun, which is defined as one Mercury year.So, for Mercury it is thesolar day, not the sidereal day that is longer than its year.(A solar day on Earth is 24 hours. A sidereal day, which is how long it takes Earth to spin on its axis, is about 4 minutes shorter.A year on Earth is about365.25 days - which is how long it takes Earth to orbit the Sun.)
How can a day be longer than a year?
Venus takes 224.7 Earth days to revolve about the Sun and 243.02 Earth days to rotate about its axis (which it does clockwise, opposite to most of the other planets). This rotation period is a "sidereal day", the time to revolve around the Sun is a Venus "year". Mercury takes 88 Earth days to go around the Sun, so its year is 88 Earth days. It spins slowly, taking 58.6 Earth days. A "solar day" on Mercury takes 176 Earth days because of this slow spin relative to the time taken to orbit. So Venus has a sidereal day longer than its year and Mercury has a solar day longer than its year.
What planet has the second shortest day?
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
Which planet's day is closest in length to its year?
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.
Do any planets have longer days or years?
No two planets in our solar system have the same length of day or length of year. Compared with Earth, these planets have longer years: Mars, Jupiter, Saturn, Uranus, Neptune. These have much longer days than Earth: Mercury and Venus. Mars has a day that's slightly longer than Earth's day. Depending on the particular definition of "day" that is used, two planets have a day that's longer than than that planet's year. They are Mercury (solar day) and Venus (sidereal day).
