On the two-year anniversar… Pluto’s distance from Earth that it makes it difficult for us to study. What missions has NASA sent to Pluto? Pluto’s moon, Charon, is named after the mythological boatman who ferried souls across the river Styx to Pluto for judgment. Pluto is a dwarf planet that lies in the Kuiper Belt. IN SPACE - JULY 14: In this handout provided by the National Aeronautics and Space Administration (NASA), a close-up image of a region near Pluto's equator shows a range of mountains rising as high as 11,000 feet (3,500 meters) taken by NASA's New Horizons spacecraft as it passed within 7,800 feet of the dwarf planet on July 14, 2015. Also considered by many to be an asteroid, Ceres, like Pluto, was also renamed as a dwarf planet in 2006. It has landscapes - rocky mountain ranges and wide plains. When it was first discovered in 1930 nobody knew how big it was, but later in the 20th century it was discovered that it was tiny in comparison to the other planets of the Solar System and that there were many other objects that were larger or of similar size in the same region. Pluto is a dwarf planet. Four scientists trawled through astronomy papers published since 1802 looking for instances of the word planet used as defined by the controversial 2006 verdict from the International Astronomical Union (IAU) that reclassified Pluto as a dwarf planet.
Pluto was publicly announced on Lowell’s birthday as the planet he had searched for and children across the U.S. learned the acronym “My Very Excellent Mother Just Served Us Nine Pizzas” to remember the order of the nine planets in our solar system.
The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet's gravity as a slingshot toward Pluto.

And as a professional astronomer, I went on to teach this nine-planet solar system model in elementary and middle schools around the globe. But the debate about Pluto's status rages on. When the IAU removed Pluto from the list of what had been nine planets in the Solar System in August 2006, the move was a corollary of its official definitions of planets and dwarf planets.

But that has not settled the matter for fans of the faraway Pluto. In early 2017, a NASA team put forward a proposal for a new definition of a planet that, if agreed upon, would mean reclassifying Pluto as a planet. Pluto is one of the most mysterious and controversial celestial objects in the solar system. "We now have a list of well over 100 recent examples of planetary scientists using the word planet in a way that violates the IAU definition, but they are doing it because it's functionally useful," lead author Philip Metzger, a planetary scientist at the University of Central Florida, said in a statement released by the university.

Is Pluto a planet? Perhaps Pluto's undeniable coolness is why people are, "The complexity of the Pluto system — from its geology to its satellite system to its atmosphere — has been beyond our wildest imagination," said Stern in a NASA statement. Perhaps Bridenstine joining Team Pluto will renew the fight.
