Can Eris be terraformed?
Can Eris be terraformed?
Conclusion. The terraforming of Eris is one of the most expensive in the Solar System and will require a continuous input of energy. However, this will provide humanity with a second outpost in the Kuiper Belt after Pluto.
How cold is Eris?
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.
What is Eris mass?
1.672 × 10^22 kg
Eris/Mass
What is Eris quizlet?
What is Eris? An extrasolar planet ejected by another solar system and captured by ours. An icy object that orbits in the Kuiper belt and is larger than Pluto. The largest known asteroid. A moon of Pluto.
Can humans live Eris?
The surface of Eris is extremely cold, so it seems unlikely that life could exist there.
What is the atmosphere of Eris?
Eris’ atmosphere is too thin to be considered a true atmosphere and appears primarily to be composed of methane that sublimates from ice on the surface. Eris lacks the gravity needed to capture gas particles as it travels through the solar system, being much smaller than any planet, and smaller than many big moons.
What is Eris composition?
Results. The surface of Eris can be modeled using two areas of distinct composition: about 50% appears to be covered with pure methane ice, while the rest of its surface would be made of an intimate mixture of methane, nitrogen and water ices, and ice tholin.
How was Eris formed?
It is believed that Eris was originally located inside the Kuiper Belt, but due to gravitational interactions with Neptune, as the Solar System was forming, the dwarf planet was forced out into the scattered disc region. Eris has a surface size similar to that of Russia.
Where is Eris?
the Kuiper Belt
Like almost all of the known dwarf planets (with the exception of Ceres), Eris lies in the Kuiper Belt, which rings the outer solar system. But Eris is even farther-flung than Pluto, circling our star about three times farther away.
How do asteroids differ from comments?
The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago.
How can we determine the reflectivity of an asteroid?
We determine an asteroid’s distance from its position in its orbit. We determine reflectivity by comparing the brightness of light in the visible spectrum to the brightness of light in the infrared spectrum. The light astronomers see shining from asteroids is reflected sunlight.
How does Eris rotate?
Eris is a trans-Neptunian object (TNO), has a high-eccentricity orbit, and is a member of the scattered disk. As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to Earth’s. However, other sources disagree on the rotation period. It has one large known moon, Dysnomia.
How much heat is needed to raise the temperature of water?
The amount of heat (or energy) needed to raise the temperature of water by one degree, varies according to where on the Celsius temperature scale you start.
What is the formula to calculate the amount of heat required?
Heat required (BTU) = m x C p x (Temperature Difference) Where C p is the heat capacity of water (1 BTU/lb/F) and m is the mass of the water (Assume 1 gal has 8.3 lb of water and the 3,412 BTU = 1 kWh)
What is the specific heat capacity of water in the calculator?
The calculators use the specific heat capacity of water of 4186 J/kg/°C (Joules per kilogram per degree Celsius). The heat capacity is largely constant in the temperature range that the calculators work (34-210°F or 1-99°C).
How much energy does it take to raise water to 2°C?
One gram of water at 1 degree Celsius needs more energy to raise its temperature to 2 degrees Celsius than it takes to raise the temperature of one gram of water at 92 degrees Celsius to 93 degrees Celsius.
