Swarms of Pluto-Size Objects Kick-Up Dust around Adolescent Sun-Like Star

Illustration of rocky objects colliding in the debris disk around a young star.

Artist impression of the debris disk around HD 107146. This adolescent star system shows signs that in its outer reaches, swarms of Pluto-size objects are jostling nearby smaller objects, causing them to collide and “kick up” considerable dust.
