Quick Answer: Which Planet Has The Longest Year?

Which planet has shortest year?

MercuryMercury is an extreme planet in several respects.

Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets..

Which planets have the longest and shortest years?

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.

What planet is the hottest?

VenusVenus 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)

What is my age on Mars?

A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.

Which two planets have the longest year?

Venus, which is roughly 38,200,000 km from Earth at its closest approach. The Planet with the Longest Year: Pluto; a year on Pluto takes 248.5 Earth years.

What is the smoothest planet?

EuropaJupiter’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.

Why is Venus called Earth’s sister?

Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.

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.

What planet is the coldest?

NeptuneNeptune, being the eighth planet in our solar system and therefore the one furthest from the sun, has the coldest average temperature (around -214°C).

What planet is the least dense?

SaturnJupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense. It’s less dense than water, which has led many people to postulate that it would float.

Is the sun a planet?

The Sun is a star. There are lots of stars, but the Sun is the closest one to Earth. It is the center of our solar system.

Are there 8 or 9 planets?

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.

Is there a 9 planet?

Planet Nine is claimed to be five to 10 times as massive as Earth, in an orbit well beyond Neptune. A team led by Kevin Napier of the University of Michigan, Ann Arbor, decided to test whether selection bias was playing a role.

What planet is the most interesting?

The best planet is Uranus—Uranus the bizarre. Uranus the unique. Saturn may be flashy and pretty, and Jupiter may be huge and dramatic, but they can’t hold a candle to Uranus’s intrigue. While all the other planets spin like tops around the sun, Uranus lies on its side.

Can we live on Neptune?

Neptune, like the other gas giants in our solar system, doesn’t have much of a solid surface to live on. But the planet’s largest moon, Triton, could make an interesting place to set up a space colony. … Though there are slight winds in Triton’s thin atmosphere, you wouldn’t feel any breeze while standing on the surface.

What planet is closest to the sun?

MercuryMercury—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.

What would Planet 9 be called?

One of those questions regards the so-called Planet Nine. … The planet is named HD 106906 b, and it orbits a binary star 336 light-years away. It has a mass of about 11 Jupiters, and it orbits the stars at a distance of more than 730 times the distance from Earth to the Sun.

Which planet makes a complete turn around the sun first?

UranusOrbit and Rotation And Uranus makes a complete orbit around the Sun (a year in Uranian time) in about 84 Earth years (30,687 Earth days). Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees—possibly the result of a collision with an Earth-sized object long ago.
