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.

How does phobos smell like?
Phobos, one of Mars' moons, is largely composed of carbon-rich materials and has a surface covered in fine dust and regolith. While it doesn't have an atmosphere to carry smells as we perceive them on Earth, scientists speculate that if you could smell it, it might have a scent reminiscent of burnt or charred materials due to its carbonaceous composition. However, without an atmosphere or life, any "smell" is purely hypothetical.
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.
How many times can Phobos fit inside Mars?
Phobos, one of Mars' moons, has a diameter of about 22.4 kilometers. Mars, in contrast, has a diameter of approximately 6,779 kilometers. To determine how many times Phobos can fit inside Mars, you can compare their volumes: Mars' volume is about 1,631,000,000 cubic kilometers, while Phobos' volume is about 5.5 cubic kilometers. This means that approximately 296 million Phobos-sized objects could fit inside Mars.
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 is Phobos day and night temperatures?
Phobos, one of Mars' moons, experiences extreme temperature variations due to its thin atmosphere. During the day, temperatures can reach around 25 degrees Celsius (77 degrees Fahrenheit), while at night, they can plummet to about -100 degrees Celsius (-148 degrees Fahrenheit). These fluctuations are a result of its close proximity to the Sun and lack of substantial atmospheric insulation.
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?
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.
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 many times can Phobos fit inside Mars?
Phobos, one of Mars' moons, has a diameter of about 22.4 kilometers. Mars, in contrast, has a diameter of approximately 6,779 kilometers. To determine how many times Phobos can fit inside Mars, you can compare their volumes: Mars' volume is about 1,631,000,000 cubic kilometers, while Phobos' volume is about 5.5 cubic kilometers. This means that approximately 296 million Phobos-sized objects could fit inside Mars.
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.
