What is the largest moon of Neptune?
Overview. Triton is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune’s gravity millions of years ago.
What are the 2 largest moons of Neptune?
With a diameter nearly that of Earth’s Moon, Triton is, by far, Neptune’s largest satellite—more than six times the size of its largest known sibling, Proteus, discovered by Voyager 2 in 1989.
Is Neptune’s moon Triton bigger than Earth?
Little was known about Triton until 1989, when the U.S. Voyager 2 probe flew within 40,000 km (24,800 miles) of it. As measured by Voyager, Triton is about 2,706 km (1,681 miles) across, which is nearly the diameter of Earth’s Moon.

What are the 4 largest moons in our solar system?
The Galilean moons (/ˌɡælɪˈliː.ən/), or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610.
Which planet has 14 moons?
The planet Neptune has 14 known moons, which are named for minor water deities in Greek mythology. By far the largest of them is Triton, discovered by William Lassell on October 10, 1846, 17 days after the discovery of Neptune itself; over a century passed before the discovery of the second natural satellite, Nereid.
Which planet has 13 moons?
Neptune has 13 known moons, though most are small and orbit closer to Neptune than its rings. Triton is Neptune’s only large moon with a diameter of 2,704 km, and Proteus and Nereid are Neptune’s second and third largest moons, respectively.
Which planet has 8 moons?
Eight of Jupiter’s moons are regular satellites, with 4 large, spherical moons, and 4 smaller moons that orbit closer to Jupiter. Jupiter has an additional 55 tiny irregular satellites.
Is Earth bigger than Titan?
Because Titan is less massive than Earth, its gravity doesn’t hold onto its gaseous envelope as tightly, so the atmosphere extends to an altitude 10 times higher than Earth’s—nearly 370 miles (600 kilometers) into space.
Which is bigger Triton or Pluto?
Then there’s Neptune’s moon Triton, a body 40 percent larger than Pluto that travels in a retrograde orbit–in the opposite direction of all the planets and major satellites in the solar system.
Is Triton colder than Pluto?
To begin, Triton is considered to be one of the coldest places in our entire Solar System. The moon’s surface temperature is about -235°C on average, while Pluto averages about -229°C. Yes, this world is colder than Pluto.
What 2 planets have 53 moons?
According to NASA, as of December of 2019, Jupiter has 79 confirmed moons and Saturn has 53. However, these numbers frequently change as more…
What planet has 200 moons?
Due to its immense size, mass, and gravitational pull, Jupiter has the most satellites of any planet in the Solar System. At present, the Jovian system includes 80 known moons, though it is estimated that it may have over 200 moons and moonlets (the majority of which are yet to be confirmed and classified).
What 2 planets have 62 moons?
Saturn’s magnificent rings owe their existence to the 62 moons of the planet, not only the close moons but also the ones orbiting much farther than the rings. Saturn’s largest moon is Titan, with lakes, a subsurface ocean, and a dense, nitrogen-rich atmosphere. In the 17th century, Christiaan Huygens discovered Titan.
What planet has 67 known moons?
Jupiter has at least 67 known moons ( http://solarsystem.nasa.gov/planets/jupiter/moons ). The largest four are called Io, Europa, Ganymede, and Callisto. These four moons are called the Galilean satellites because they were first seen in 1610 by the astronomer Galileo Galilei.
Who have 16 known moons?
Which planet has 16 moons? Among the planets far from the Sun, Jupiter has 16 known moons, Saturn has 18, Neptune has eight and Uranus beats the record, with 21. The only exception is the last planet in the solar system, Pluto, which has only one solitary moon – the planet is small and failed to attract other stars.
Which planet has 16 known moons?
So these 11 (which are most probably asteroids that have been captured by Jupiter’s gravity) will most probably be accepted in the near future and take the official list of Jupiter’s moons from 16 to 27.
What is the 9th largest moon?
Rhea (/ˈreɪ. ə/) is the second-largest moon of Saturn and the ninth-largest moon in the Solar System.
What is the biggest moon in the planet?
Ganymede. Ganymede is the largest moon in the solar system (larger than the planet Mercury), and is the only moon known to have its own internally generated magnetic field.
