Triton retains an atmosphere primarily due to its significant gravity and relatively low temperature, which allows it to hold onto gases like nitrogen. Its geologic activity, including geysers that release nitrogen and possibly other gases, also contributes to maintaining its atmosphere. In contrast, Phobos is much smaller and has insufficient gravity to retain an atmosphere, as its weak gravitational pull allows any gases to escape into space easily. Additionally, Phobos lacks significant geologic activity that could replenish any transient atmosphere it might have had.

What moon is more circular Phobos or Deimos?
Deimos is more circular than Phobos. Deimos has a nearly circular shape with an eccentricity of only 0.00033, while Phobos is more elongated with an eccentricity of about 0.0151.
Two moon of Mars?
The two moons of Mars are Phobos and Deimos. Phobos is the larger of the two moons and is closer to Mars, while Deimos is smaller and further away. Both moons are thought to be captured asteroids due to their irregular shapes and composition.
What was mars moons named after?
The two moons of Mars, Phobos and Deimos, are named after the sons of the Greek god of war, Ares, who is equivalent to the Roman god Mars. "Phobos" means fear or panic, while "Deimos" means terror or dread.
Does Triton have Volcanoes and Earthquakes?
Yes, Triton is believed to have active ice volcanoes, called cryovolcanoes, that erupt a mixture of water, ammonia, and other volatiles. While there is no direct evidence of earthquakes on Triton, the volcanic activity and tidal forces from Neptune could potentially cause some seismic activity.
What are the closest two objects to Neptune?
Neptune's closest objects are its largest moon Triton and the dwarf planet Eris. Triton is a significant moon with a retrograde orbit, while Eris is one of the largest known dwarf planets in our solar system.
Is Phobos larger than Deimos?
Yes, Phobos is bigger than Deimos. Phobos mass is .00000018 and Deimos mass is .000000024. Phobos is 12X8 (miles) and Deimos is 7X6
Name the 2 satellite of mars?
The two moons of Mars are named Phobos and Deimos. Phobos is the larger and closer of the two, while Deimos is smaller and farther from Mars.
What moon is more circular Phobos or Deimos?

How large is phobos compared to the earth?
Phobos, one of Mars' moons, is significantly smaller than Earth. Phobos has a diameter of about 22.4 kilometers, while Earth's diameter is approximately 12,742 kilometers. This means that Phobos is roughly 570 times smaller than Earth in terms of diameter.
Which one is bigger Phobos or Deimos?
Phobos, It is also the moon that orbits closer to Mars... yes i know Deimos is a loner.
Which of Mars' moons is bigger in size?
Phobos is the larger of Mars' two moons. It has a diameter of about 22.4 kilometers, while Deimos is smaller with a diameter of about 12.4 kilometers.
Why does the earth not lose its heat as quickly at night as the moon does?
The Earth retains heat better due to its thicker atmosphere and higher heat capacity compared to the moon. The atmosphere acts as a barrier, trapping heat on Earth, while the moon has no atmosphere to retain heat, causing rapid heat loss at night.
Known satellites for Mars?
Some known satellites for Mars include Phobos and Deimos. Phobos is the larger and closer of the two, while Deimos is smaller and farther away. Both satellites are irregularly shaped and are thought to be captured asteroids.
What moons circle mars?
Mars has two small moons named Phobos and Deimos. Phobos is the larger of the two moons and orbits very close to Mars, while Deimos is smaller and orbits further away. Both moons are thought to be captured asteroids.
How much bigger is earth's moon compared to phobos?
Earth's Moon has a diameter of about 3,474 kilometers, while Phobos, one of Mars' moons, has a much smaller diameter of approximately 22.4 kilometers. This means the Moon is roughly 155 times wider than Phobos. In terms of volume and mass, the Moon is vastly larger, making it a significant satellite compared to the tiny Phobos.
