Which planets have the longest and shortest years?
Mercury has the shortest year (88 Earth days), and Neptune has the longest year (165 Earth years). Planets closer to the Sun have shorter year, because their orbits are smaller. Mercury, the innermost planet in the solar system, completes an orbit in 88 days.
Which planet takes the longest period?
Neptune has the longest period of revolution (164 years) around the sun.
Which planet has the longest year compared to Earth?
Kepler-421b, a newly discovered planet that’s outside of our solar system, takes the cake for exoplanet with the longest year. It takes 704 Earth days, or about 2 Earth years, for the exoplanet to make one revolution around its star.
Which planet has shortest year?
Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
Which planet has the shortest period?
The planet with the shortest orbital period (year) is Mercury. The innermost planet in our Solar System completes its eliptical orbit around the Sun once every 87 (Earth) days 21 hours.
Which planet is the hottest?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet.
Which is called the blue planet?
Over 71 percent of the Earth is covered with water. Therefore from outer space it appears blue and so Earth is called the ‘Blue Planet’.
Which planet lasts longer than a year?
A day on Venus is longer than a year That’s 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.
Does Pluto or Neptune have a longer year?
And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days). Sometimes Neptune is even farther from the Sun than dwarf planet Pluto. Pluto’s highly eccentric, oval-shaped orbit brings it inside Neptune’s orbit for a 20-year period every 248 Earth years.
Does Earth have a longer year than Mercury?
A year is the time it takes the earth to make one revolution – a little over 365 days. We all learn in grade school that the planets move at differing rates around the sun. While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days.

Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
What planet has no seasons?
As the closest planet to the sun, Mercury’s climate varies significantly throughout its year, which equates to 88 Earth days. Mercury is also the only planet in our solar system without any tilt, so technically lacks seasons.
Which planet has no atmosphere?
