When did New Horizons go to Pluto?
July 14, 2015
New Horizons reached Pluto on July 14, 2015, becoming the first spacecraft to barnstorm the dwarf planet. Less than four years later, on Jan. 1, 2019, it passed the peanut-shaped, 36-km long Kuiper Belt object known as Arrokoth, a rocky, icy body in the river of similar comet-like objects that circles the solar system.
Where did New Horizons go after Pluto?
the Kuiper Belt
The New Horizons mission is the first to visit the the Kuiper Belt, a ring of small, icy worlds beyond the orbit of Neptune. After zooming past Pluto, the largest world in the Kuiper Belt, the plutonium-powered spacecraft journeyed farther from the sun and flew by a peanut-shaped object named Arrokoth on Jan. 1, 2019.
Why did New Horizons not orbit Pluto?
A key finding from New Horizons is that Pluto and its moons, like other planets closer to home, are too complex and too compelling to be left to a single first flyby reconnaissance. Pluto beckons, and we must return with an orbiter.
When did Pluto change from a planet to dwarf planet?
In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of “dwarf planet.” This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.
When was Pluto redefined as a dwarf planet?
When Pluto was reclassified in 2006 from a planet to a dwarf planet, there was widespread outrage on behalf of the demoted planet. As the textbooks were updated, the internet spawned memes with Pluto going through a range of emotions, from anger to loneliness.
What is spacecraft sent to Pluto?
New Horizons is a NASA spacecraft that was the first to visit dwarf planet Pluto in July 2015. Its pictures of the dwarf planet’s icy surface, as well as observations of Pluto’s moon Charon, are revolutionizing our understanding of solar system objects far from the sun.
Where is New Horizons probe now?
Moving on from its Pluto mission, New Horizons is now en route to the Kuiper Belt, right at the fringes of the solar system.
