The research craft New Horizons should reach Pluto by New Horizons has already discovered two new moons of Pluto, currently called P4 and P5. Pluto already had three known moons before the mission: Hydra, Nix, and Charon.
What Are the Elements of Uranus? Geology Facts on Neptune. Does It Rain on Pluto? Amazing Facts on Saturn. Characteristics of the region suggest that it was formed by an ancient impact and suggest that the water ice welled up from below after the impact.
So, does Pluto have storms? Perhaps it depends on how exactly you define a storm. Whether or not it ever has howling blizzards, it certainly has some rugged weather. Interested in all things in outer space and exploration? We are too. Take a look at open positions at Northrop Grumman and consider joining our team. A new study reveals details about a species of prehistoric rhino that lived in the Tibetan plateau.
In the complex carbon molecule methanol a key molecule of life was discovered in a developing solar. Once upon a time, maps were full of blank space, vast regions that had never been From an average distance of 3. One astronomical unit abbreviated as AU , is the distance from the Sun to Earth.
From this distance, it takes sunlight 5. There is a moment each day near sunset here on Earth when the light is the same brightness as midday on Pluto.
Find out when you can experience "Pluto time" where you live. Pluto's orbit around the Sun is unusual compared to the planets: it's both elliptical and tilted. Pluto's year-long, oval-shaped orbit can take it as far as One AU is the mean distance between Earth and the Sun: about 93 million miles or million kilometers. But on average, Pluto is 3. From to , Pluto was near perihelion, when it is closest to the Sun. During this time, Pluto was actually closer to the Sun than Neptune.
One day on Pluto takes about hours. Its axis of rotation is tilted 57 degrees with respect to the plane of its orbit around the Sun, so it spins almost on its side. Pluto also exhibits a retrograde rotation; spinning from east to west like Venus and Uranus. This moon system might have formed by a collision between Pluto and another similar-sized body early in the history of the solar system. Charon, the biggest of Pluto's moons, is about half the size of Pluto itself, making it the largest satellite relative to the planet it orbits in our solar system.
It orbits Pluto at a distance of just 12, miles 19, kilometers. For comparison, our Moon is 20 times farther away from Earth. Pluto and Charon are often referred to as a double planet. Charon's orbit around Pluto takes hours — the same time it takes Pluto to complete one rotation. This means Charon neither rises nor sets, but hovers over the same spot on Pluto's surface.
The same side of Charon always faces Pluto, a state called tidal locking. Pluto's other four moons are much smaller, less than miles kilometers wide. She loves all things space and astronomy-related, and enjoys the opportunity to learn more.
