A six-year-old girl is leading the charge to make Pluto, downgraded to a dwarf planet in 2006, the ninth planet in our solar system again. Young Cara O’Connor of Ireland wants to one day grow up to be a NASA astronaut, and she wrote a letter to the space agency requesting that they make Pluto a planet again.

It is not exactly up to NASA, as Pluto was downgraded by the International Astronomical Union, which decided that Pluto simply did not meet the criteria for a planet. However, Cara thinks that NASA should do what they can to “fix this problem” and “make Pluto a planet again.”

“I really think Pluto should be a main planet again like Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus & Neptune, because in one video I watched called ‘Let’s go meet the planets,’ Pluto was at the very end,” she wrote, according to an Economic Times report.

She said it was “mean” to put Pluto “in the trash can.” Her letter got a response from James Green, Director of NASA’s Planetary Science Division.

“I agree with you that Pluto is really cool — in fact, who would have believed that Pluto has a heart? … It’s a fascinating world that appears to be constantly changing. To me, it’s not so much about whether Pluto is a dwarf planet or not; it’s that Pluto is a fascinating place that we need to continue to study,” Green wrote according to the report.
