London, June 11 : An astronomer has suggested that Nix and Hydra, two of Pluto’s moons, are spray-painting the planet and Charon with their dust.
According to a report in New Scientist, Alan Stern at the Lunar and Planetary Institute in Houston, Texas, US, has come up with this theory.
Pluto’s dazzling red stands in sharp contrast to the greys of its three moons Hydra, Nix and Charon.
The moons’ similarity was thought to be because the trio was created at the same time from the same material in a massive smash in the early solar system.
Now, Stern has determined that the similarity is due to Nix and Hydra throwing up some dust at Charon, as well as Pluto.
