NASA Administrator Jared Isaacman has reaffirmed his stance that Pluto should be considered a planet during a US Senate hearing on April 28. The hearing was part of a review of President Donald Trump's proposed budget for NASA. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union. The decision was based on Pluto's inability to 'clear its orbit of debris'. Isaacman, a private astronaut and NASA's administrator since December 2025, has been a vocal supporter of restoring Pluto's planetary status. Pluto is a frigid world with craters and glaciers, located in the Kuiper Belt beyond Neptune's orbit.
