Does sunlight reach Eris?
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. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight more than nine hours to travel from the Sun to the surface of Eris.
How many light years is Eris from the sun?
Eris is about 68 AU away from the sun, and presently about 95.1 AU from the Earth. It takes about 13 hours for light to travel from Eris to us.
What is the surface of Eris like?
Researchers believe Eris’ surface is probably composed of a nitrogen-rich ice mixed with frozen methane in a layer less than 1 millimeter thick. This ice layer could result from the dwarf planet’s atmosphere condensing as frost onto its surface periodically as it moves away from the sun, they said.
Why can’t humans live on Neptune?
The answer is that we couldn’t live on the planet Neptune for a few reasons. It’s far too cold, there’s no oxygen and it’s primarily made up of ice! So, it’s not going to be suitable for colonization by humans any time soon, even though it is within our solar system.
What happen if we fall into Neptune?
As a gas giant (or ice giant), Neptune has no solid surface. If a person were to attempt to stand on Neptune, they would sink through the gaseous layers. As they descended, they would experience increased temperatures and pressures until they finally touched down on the solid core itself.
Can you swim on Neptune?
Being an ice giant, there is no water on the surface of Neptune. Having a surface temperature of −201 oC any water on Neptune will be frozen. Extraterrestrial liquid water is believed to be beneath the ice surfaces of the Jovian moons Europa and Ganymede.
Does Neptune have oxygen?
Yes, there is lots of oxygen in Neptune, but almost none of it is gaseous or in its atmosphere. Neptune’s atmosphere is made up of Hydrogen (80%), Helium (19%), and Methane (1%). While there are other trace gases, they make up a fraction of a percent.
