Can moons have moons?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite

sub-satellite

A subsatellite, also known as a submoon, or moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet. It is inferred from the empirical study of natural satellites in the Solar System that subsatellites may be rare, albeit possible, elements of planetary systems.

can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

Do any moon have moons?

In the Solar System, we have the central Sun, a great many planets, asteroids, Kuiper belt objects, and moons. While most of the planets have moons, and some of the Kuiper belt objects and even asteroids have natural satellites that orbit them, there are no known "moons of moons" out there.

Can a moon have moons of its own?

Yes, it is possible for a moon to itself have moons and/or rings, and there are a few places where scientists have suggested that this is (or was) the case. However, moons tend to rotate slowly, and this makes it difficult for a moon's moon to find a stable orbit.

What if a moon has moons?

According to the paper, what they found is that in most cases there's just not enough space for a submoon to orbit another moon. Tidal forces would pull the little moon toward the host planet, ripping the mini moon to pieces. For a submoon to survive, it needs to be small—about six miles in diameter or less.

Can moons have sub moons?

Only large moons on wide-separation orbits can host long-lived submoons. This is mainly because massive, distant moons have larger Hill radii that provide more stable volume for submoons. Most of the large regular moons of the giant planets are too close to their host planets to host submoons.

Can Moons Have Moons?

What is it called when a moon has a moon?

A subsatellite, also known as a submoon, or moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet.

Does Earth have 3 moons?

The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.

Can humans live on Titan?

Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying "In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization." The atmosphere contains plentiful nitrogen and methane.

Can there be a gas moon?

Most moons don't reach this minimum size limit. As the moons are small their gravitational influence usually cannot rival that of their parent planets. This means that the planet usually strips any gas away from the moons around it. A gas moon, in the style of a gas planet could not exist.

Why is Pluto not a planet?

According to the IAU, Pluto is technically a “dwarf planet,” because it has not “cleared its neighboring region of other objects.” This means that Pluto still has lots of asteroids and other space rocks along its flight path, rather than having absorbed them over time, like the larger planets have done.

Can a moon become a planet?

But we're talking really strange. Eventually, if Earth and its Moon survive long enough, the Moon will have to be reclassified as a planet, said Gregory Laughlin, an extrasolar planet researcher at the University of California, Santa Cruz.

Did the Earth used to be purple?

Hence, it's possible that there was a stage of our planet's history that the researchers dubbed “Purple Earth”. That time would date somewhere between 2.4 to 3.5 billion years ago, prior to the Great Oxygenation Event, which was likely due to the rise chlorophyll-based photosynthesis.

What if Venus had a moon?

If Earth had been orbited by a low flying potato shaped body, things would have been quite different. If Venus had a moon, we should suppose the system would look a lot like the Earth - Moon system : so close to the sun, it would be unlikely to have a moon forming far from the planet like in the outer solar system.

Who invented the name of Earth?

The name "Earth" is derived from both English and German words, 'eor(th)e/ertha' and 'erde', respectively, which mean ground. But, the handle's creator is unknown. One interesting fact about its name: Earth is the only planet that wasn't named after a Greek or Roman god or goddess.

What is Earth's moon name?

Earth has one moon. We call it "the Moon" because for a long time it was the only one we knew about. Many languages have beautiful names for our Moon. It is "Luna" in Italian, Latin, and Spanish, "Lune" in French, "Mond" in German, and "Selene" in Greek.

Which planet has 62 moons?

Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena. The moons shape, contribute and also collect material from Saturn's rings and magnetosphere.

Can we terraform Titan?

To break it down, only Enceladus and Titan appear to be viable candidates for terraforming. However, in both cases, the process of turning them into habitable worlds where human beings could exist without the need for pressurized structures or protective suits would be a long and costly one.

Is there any oxygen on Titan?

Titan's atmosphere is much colder, however, having a temperature at the surface of 94 K (−290 °F, −179 °C), and it contains no free oxygen. A troposphere analogous to Earth's extends from Titan's surface to an altitude of 42 km (26 miles), where a minimum temperature of 71 K (−332 °F, −202 °C) is reached.
