Can a gas giant have a moon?
All four gas giants have rings and moons. Saturn’s rings, made of mostly ice, are the most spectacular, and the only ones known before the 1970s. As of 2004, Jupiter was thought to have the most moons, with more than sixty discovered!
Could a gas giant have an Earthlike moon?
My research tells me that a moon around a gas-giant is not likely to be larger than 1:10,000th of the mass of its parent. If this is true, an Earth-like moon is unlikely to form around anything with less than 30 Jupiter masses, which puts the parent planet in the brown dwarf range.
Could a planet orbit a gas giant?
Originally Answered: Is it possible for an earth sized planet to orbit as a moon around a gas giant? On a Super-Jupiter or Brown Dwarf yes, (provided that your Planet is outside the radiation belt). Natural Moons of Gas Giants their mass should be less than 0.0001 of the mass of the gas Giant.
What would happen if a human went to Jupiter?
Jupiter’s deep atmosphere absorbs radio waves, so you’ll be shut off from the outside world— unable to communicate. Once you’ve reached 2,500 miles down, the temperature is 6,100 ºF. That’s hot enough to melt tungsten, the metal with the highest melting point in the Universe.
Are any moons made of gas?
Our solar system’s moons all are rocky or icy objects. The newly discovered exomoon and the planet it orbits, estimated to be several times the mass of our solar system’s largest planet Jupiter, are both gaseous, an unexpected pairing. They are located 8,000 light years from Earth.
Is Venus a gas giant?
Venus has the most massive atmosphere of all the terrestrial planets. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen….What is Venus made of?

Is Pluto a gas giant?
So inconspicuous that it was not discovered until 1930, Pluto is not a gas giant planet like all the others in the outer solar system. Instead it is a small, rocky world about the size of Earth’s Moon. Pluto now seems to be about 3000 to 3500 kilometers (1900 to 2200 miles) in diameter.
