Question: What Is The Largest Moon In The Universe?

Biggest Moons In Our Solar System

  • Ganymede. Ganymede is the largest of Jupiter’s 79 moons as well as by far the largest moon in the solar system.
  • Titan. Titan orbits Saturn and is the second largest moon with a diameter of 5,150 km.
  • Callisto.
  • Io.
  • Other Large Moons.

How big is Ganymede compared to our moon?

Ganymede is larger than both Mercury and Pluto, and is 2/3 the size of Mars with a diameter of 5,268 km (3,273 miles) – 8% larger than Mercury. It has the highest mass of all planetary satellites and has more than twice the mass of the Earth’s Moon.

Which is bigger Titan or Ganymede?

Frequently described as a planet-like moon, Titan is 50% larger than Earth’s moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter’s moon Ganymede, and is larger than the planet Mercury, but only 40% as massive. Titan is primarily composed of ice and rocky material.

Can humans breathe on Europa?

Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.

Which moon is most habitable?

Enceladus Saturn Enceladus – potential habitability

Does Ganymede have life?

Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. Ganymede is composed of approximately equal amounts of silicate rock and water ice.

Can we live Ganymede?

In 1996, astronomers using the Hubble Space Telescope found evidence of a thin oxygen atmosphere. However, it is too thin to support life as we know it; it is unlikely that any living organisms inhabit Ganymede. Magnetosphere: Ganymede is the only satellite in the solar system to have a magnetosphere.

Does any planet have water?

Using such methods, many scientists infer that liquid water once covered large areas of Mars and Venus. Water is thought to exist as liquid beneath the surface of some planetary bodies, similar to groundwater on Earth.

Can we live on Titan?

Whether there is life on Titan, the largest moon of Saturn, is at present an open question and a topic of scientific assessment and research. Titan is far colder than Earth, and its surface lacks stable liquid water, factors which have led some scientists to consider life there unlikely.

Is Earth’s moon the biggest?

It is the largest moon in the Solar System relative to the size of its planet, though Charon is larger relative to the dwarf planet Pluto, at 1/9 Pluto’s mass. The Earth and the Moon’s barycentre, their common centre of mass, is located 1,700 km (1,100 mi) (about a quarter of Earth’s radius) beneath Earth’s surface.

Why is Titan’s atmosphere so thick?

It supports opaque haze layers that block most visible light from the Sun and other sources and renders Titan’s surface features obscure. The atmosphere is so thick and the gravity so low that humans could fly through it by flapping “wings” attached to their arms.

Is Ceres bigger than the moon?

It was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was still more than ten times as massive as the largest object in the asteroid belt, Ceres, it had one-fifth the mass of Earth’s Moon.

What is the smallest moon in Jupiter?


Is the sun bigger than Jupiter?

Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.

Does life exist Europa?

So far, there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth’s deep-ocean hydrothermal vents.

Can we live on Jupiter moon Europa?

Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. Europa’s geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.

Can humans live on Venus?

Habitability of its atmosphere. Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.

How many planets can support life?

In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be orbiting Sun-like stars.

Can life support Mars?

The confirmation that liquid water once flowed on Mars, the existence of nutrients, and the previous discovery of a past magnetic field that protected the planet from cosmic and solar radiation, together strongly suggest that Mars could have had the environmental factors to support life.

Should we populate the moon?

The energy required to send objects from the Moon to space is much less than from Earth to space. This could allow the Moon to serve as a source of construction materials within cis-lunar space. Rockets launched from the Moon would require less locally produced propellant than rockets launched from Earth.
