What is the order of the 9 planets?
What is the order of the 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
What is Earth’s second moon called?
Cruithne
Its period of revolution around the Sun, approximately 364 days in the early 21st century, is almost equal to that of Earth. Because of this, Cruithne and Earth appear to “follow” each other in their paths around the Sun. This is why Cruithne is sometimes called “Earth’s second moon”.
Would Venus be habitable?
A sophisticated climate model suggests that liquid-water oceans never formed on Venus, and that some planets outside the Solar System that were thought to be habitable might not be.
What are the moons of Jupiter and Saturn called?
Many of Jupiter’s outer moons have highly elliptical orbits and orbit backwards (opposite to the spin of the planet). Saturn, Uranus and Neptune also have some irregular moons, which orbit far from their respective planets. Saturn has two ocean moons – Enceladus and Titan.
Which of Jupiter’s moons has an elliptical orbit?
Many of Jupiter’s outer moons have highly elliptical orbits and orbit backwards (opposite to the spin of the planet). Saturn, Uranus and Neptune also have some irregular moons, which orbit far from their respective planets.
What is the mass distribution of the Neptunian moons?
The mass distribution of the Neptunian moons is the most lopsided of the satellite systems of the giant planets in the Solar System. One moon, Triton, makes up nearly all of the mass of the system, with all other moons together comprising only one third of one percent.
What are the inner moons of Uranus and Neptune like?
In the realm of the ice giants, Uranus’s inner moons appear to be about half water ice and half rock. Miranda is the most unusual; its chopped-up appearance shows the scars of impacts of large rocky bodies. Neptune’s moon Triton is as big as Pluto and orbits backwards compared with Neptune’s direction of rotation.
