How big is Ganymede compared to the Earth?
If Ganymede were orbiting the Sun it would be a planet. 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?
In the Solar System
|Enceladus||Saturn||Enceladus – potential habitability|
|Titan||Saturn||Life on Titan|
|Callisto||Jupiter||Callisto – potential habitability|
|Ganymede||Jupiter||Ganymede – Subsurface oceans|

Is Earth’s moon bigger than Pluto?
Pluto is not very big. It is only half as wide as the United States. Pluto is smaller than Earth’s moon. This dwarf planet takes 248 Earth years to go around the sun.
Are any moons bigger than Earth?
However, not all of the moons are smaller than all of the planets. There are seven moons in our Solar System, including our own Moon, that are larger than Pluto. Jupiter’s moon Ganymede is the largest moon in the Solar System, and Ganymede as well as Saturn’s moon Titan are both larger than Mercury and Pluto.
Which planet has the largest moon in the solar system?
One of Jupiter’s moons, Ganymede, is the largest moon in the Solar System. Ganymede has a diameter of 3270 miles (5,268 km) and is larger than the planet Mercury. It has a rocky core with a water/ice mantle and a crust of rock and ice.
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.
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.
What is the most massive object in our solar system?
Solar System objects more massive than 1021 kilograms (one yottagram [Yg]) are known or expected to be approximately spherical.
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.
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.
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.
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.
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.
Could Venus have supported life?
Until the mid 20th century, the surface environment of Venus was believed to be similar to Earth, and hence it was widely believed that Venus could harbor life. In 1870, the British astronomer Richard Proctor said the existence of life on Venus was impossible near its equator, but possible near its poles.
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.
Which planet has the largest volcano?
What is Ceres atmosphere made of?
Ceres appears to be differentiated into a rocky core and an icy mantle, and may have a remnant internal ocean of liquid water under the layer of ice. The surface is a mixture of water ice and various hydrated minerals such as carbonates and clay.
Is the planet Neptune bigger than Earth?
In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth, slightly more massive than its near-twin Uranus.
What is the biggest moon of Jupiter?
Can we colonize Titan?
Saturn’s largest moon Titan is one of several candidates for possible future colonization of the outer Solar System. According to Cassini data from 2008, Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth.
Was there once a planet between Mars and Jupiter?
Phaeton (or Phaëton) was the hypothetical planet theorized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the dwarf planet Ceres).
Why was Pluto not considered a planet?
In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet” formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
Why is haumea not a planet?
Haumea is a plutoid, a dwarf planet located beyond Neptune’s orbit. It is classified as a dwarf planet because it is presumed to be massive enough to have been rounded by its own gravity into a shape in hydrostatic equilibrium, but not massive enough to have cleared its neighbourhood of similarly sized objects.
