Which terrestrial planet has the longest year?

Answer 1

Pluto has the longest year, if it was still a planet that is, equal to 248.76 Earth years.

Since Pluto is no longer considered a planet, the planet with the longest year is Neptune, at 164.8 Earth years per revolution around the Sun.

Answer 2

Pluto has the longest year because its year is 247.7 earth years and also because the sun has not had enough force and power to make it orbit faster. (That is if it was still a planet) If you conclude that Pluto is not a planet to you, well than Neptune has the longest year which is 164.79 earth years (60,148 Earth days).

Answer 3

The planet in our solar system with the longest year is Neptune, the planet that is furthest away from the Sun, with an orbit of 165 Earth years. In a similar way, the planet which has the shortest year is Mercury as it is at the least distance from the sun. Therefore, Mercury is the planet which takes the least time to revolve with a year length of 88 days.

Answer 4

Mars has the longest year of the four terrestrial planets.

Answer 5

The planet furthest away from the sun, Neptune, has the largest orbit, and therefore has the longest year.

Answer 6

Mercury has the longest year among the terrestrial planets, lasting about 88 Earth days.

Answer 7
