# How long does it take for Eris to rotate on its own axis?

## How long does it take for Eris to rotate on its own axis?

Orbit and Rotation As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to ours.

How long it takes each planet to rotate on its axis?

The Days (And Years) Of Our Lives

Planet Rotation Period Revolution Period
Venus 243 days 224.7 days
Earth 0.99 days 365.26 days
Mars 1.03 days 1.88 years
Jupiter 0.41 days 11.86 years

### How big is Pluto vs Eris?

The observations helped scientists determine that Eris’ diameter is 1,445 miles (2,326 kilometers), give or take 7 miles (12 km). That makes it slightly smaller than Pluto.

How fast does Eris move?

#### Which is the 10th planet?

Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System’s tenth planet….Eris (dwarf planet)

Discovery

Pronunciation /ˈɛrɪs/, /ˈɪərɪs/

How often does Eris rotate around the Sun?

The plane of Eris’ orbit is well out of the plane of the solar system’s planets and extends far beyond the Kuiper Belt, a zone of icy debris beyond the orbit of Neptune. As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to ours.

## How long does it take for the Earth to rotate on its axis?

Although it takes Earth 23 hours and 56 minutes and 4.09 seconds to spin 360 degrees on its axis, In light of this, does the earth take exactly 24 hours to rotate? Earth’s rotation or spin is the rotation of planet Earth around its own axis.

What is the orbit of the dwarf planet Eris?

Eris has an unusual orbit. The orbit is tilted at an angle of 44 with respect to the ecliptic, the imaginary plane in which Earth and most other planets move. The orbit is highly eccentric (e = 0.44), bringing the object within 38 AU of the Sun at perihelion and sending it out beyond 97 AU at aphelion.

### How often does the Sun rotate on its axis?

The Sun rotates on its axis once in about 27 days. Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun’s equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). Is there oxygen on Saturn?
