Which planet has the longest day and the shortest year? The answer to both questions is Mercury. It orbits the Sun every 88 days, and a Solar Day on Mercury lasts for two orbits which is 176 days.
Which planets have the shortest years?
The Planet with the Shortest Year:
Mercury; a year on Mercury takes only 88 Earth days.
Which planets have the longest year?
Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
Which planets have the longest and shortest days?
Jupiter has the shortest day of all the planets. A day on Jupiter lasts only nine hours and 55 minutes. Venus has the longest day of all the planets.
Which planet has the longest and shortest revolution?
Jupiter has the shortest revolution period and Venus has the longest.
Is there a 9 planet?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
What is the smoothest planet?
Jupiter’s large icy moon Europa has the smoothest surface of any solid body in the Solar System. The only prominent relief on its surface are ridges a few hundred metres in height.
How old would I be on Pluto?
The Days (And Years) Of Our Lives
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Saturn | 0.45 days | 29.46 years |
| Uranus | 0.72 days | 84.01 years |
| Neptune | 0.67 days | 164.79 years |
| Pluto | 6.39 days | 248.59 years |
Which planet day is longer than year?
On Venus, one rotation on its axis takes the equivalent of 243 Earth days and the planet’s orbit around the Sun takes the equivalent of 225 Earth days.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
How long is 1 hour in space?
1 hour in space is 7 years on earth.
Is a day exactly 24 hours?
On Earth, a solar day is around 24 hours. However, Earth’s orbit is elliptical, meaning it’s not a perfect circle. That means some solar days on Earth are a few minutes longer than 24 hours and some are a few minutes shorter. … On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
What planet has the shortest day?
The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
What planet is closest to the sun?
Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Which is the closest celestial body to our earth?
Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.
Which planet spins the fastest?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
