What is the temperature of Eris?

What is the temperature of Eris?

Due to Eris’s distant eccentric orbit, its surface temperature is estimated to vary between about 30 and 56 K (−243.2 and −217.2 °C). Unlike the somewhat reddish Pluto and Triton, Eris appears almost white.

How cold is Eris in Fahrenheit?

Astronomers estimated that the side of the dwarf planet facing the sun likely gets no warmer than minus 396 degrees Fahrenheit (minus 238 degrees Celsius), while temperatures on the night side would be even lower.

What is the coldest dwarf planet in the universe?

NASA’s Hubble Space Telescope has also revealed evidence that Pluto’s crust could contain complex organic molecules. Pluto’s surface is one of the coldest places in the solar system, at roughly minus 387 degrees Fahrenheit (minus 232 degrees Celsius).

What is the temperature of dwarf planets?

Dwarf Planets

Is Eris hot or cold?

Eris is the same size as Pluto, but three times further from the Sun! It’s so far away, we don’t know much about this extremely cold and remote dwarf planet. Eris is the most distant dwarf planet, located beyond the orbit of Neptune. It was discovered in 2005 and was originally classified as a planet.

Why is Eris not the coldest dwarf planet?

It takes 557 Earth years for Eris to make one orbit around the Sun. It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from -217 degrees Celsius to -243 degrees Celsius.

Is Eris or Pluto bigger?

Eris is one of the largest known dwarf planets in our solar system. It’s about the same size as Pluto but is three times farther from the Sun. At first, Eris appeared to be larger than Pluto. Pluto, Eris, and other similar objects are now classified as dwarf planets.

Is Pluto cold or hot?

Pluto, along with many other dwarf planets in the outer solar system, is often thought of as dark, icy and barren – with a surface temperature of just -382 degrees Fahrenheit (-230 degrees Celsius).

What is the lowest temperature on Pluto?

All planets have temperature changes related to their seasons; some changes are more extreme than others. At its warmest, when it is closest to the sun, Pluto can reach temperatures of minus 369 degrees Fahrenheit (minus 223 degrees Celsius). At its coolest, temperatures can fall to minus 387 degrees F (minus 233 C).

Is Pluto bigger than Eris?

Eris is one of the largest known dwarf planets in our solar system. It’s about the same size as Pluto but is three times farther from the Sun. Pluto, Eris, and other similar objects are now classified as dwarf planets.

What is the closest planet or dwarf planet to Eris?

Eris is currently classified as a trans-Neptunian dwarf planet (plutoid) one of the 5 known dwarf planets discovered as of 2017. It is also (currently) the furthest dwarf planet from the Sun (three times the distance of Earth to Pluto) to be discovered with Ceres being closest.

What is the average temperature of a dwarf planet?

The average temperature on this dwarf planet is around 42 K. The minimum approximate temperature is around 30 K, whereas the maximum temperature could reach up to 55 K on it. Eris dwarf planet has only one known moon and its name is “Dysnomia”.

What planet is the coldest dwarf planet?

Pluto is a dwarf planet made of ice and rock. Originally thought to be the ninth planet, Pluto is the furthest from the sun and has recorded the coldest temperatures at an average of -225ºC.

Is the dwarf planet Eris bigger than Earth’s Moon?

Eris, like Pluto, is a little smaller than Earth’s Moon. If the Earth were the size of a nickel, Eris would be about as big as a popcorn kernel. From an average distance of 6,289,000,000 miles (10,125,000,000 kilometers), Eris is about 68 astronomical units away from the Sun.
