Does Pluto or Neptune have a longer year and why?

Answer 1

Neptune has a longer year than Mercury. The closer to the sun a planet is, the faster the orbit and shorter the year. Neptune's orbital period (year) is a little under 165 Earth years. Mercury orbits the sun in just under 88 days.

Answer 2

Because it is furthest from the Sun and has the longest distance to travel. This is because, compared to the inner planets of our solar system, Pluto takes the longest to make a full orbit around the sun (equivalent to 248.5 Earth years).

Answer 3

Pluto has a longer year than Neptune, because Pluto (usually!) is beyond Neptune's orbit.

Pluto has a very eccentric orbit; for part of its orbit, Pluto is actually closer to the Sun than Neptune. But Pluto makes up for it by swinging far outside of Neptune's orbit for most of the Plutonian "year".

Answer 4

A year is the time it takes for a planet to circle the sun once. Venus and Neptune both orbit the sun, but Neptune is several times further away from it, and thus the circumference of its path is also much longer, and thus it takes a much longer time for Neptune to make it's round around the sun.

Answer 5

Pluto has a far greater distance to travel around the sun than earth because it is so far away. A year on any planet is just how long it takes the planet to get back to where it was. It takes earth 364 1/4 days to go one full revolution around the sun, whereas it takes pluto 248 earth years to revolve around the sun, or 90,334 days.

Answer 6

Neptune's year is longer than Earth's year because it takes Neptune much longer to orbit the Sun once. Neptune is farther away from the Sun than Earth is.

So, Neptune has to travel much farther to complete an orbit around the Sun and also Neptune travels much more slowly in its orbit.

The time to orbit the Sun is Neptune's "year". It's about 165 times as long as an Earth year.

Answer 7

Because it is further from the sun.

The further a planet, dwarf planet, moon and so on are from the sun, the longer it takes to orbit the sun. One year is one whole orbit around the sun, for example, the Earth takes 12 months to orbit the sun, so 12 months on Earth is one year.

Answer 8

one day on Neptune is equel to how man =y hours/days on earth

Answer 9

Much longer, about 165 Earth years.
