Pluto TV will celebrate to 10 years of free TV streaming by going back to its Pluto planet roots.

Pluto may have lost its status as a full-fledged planet in 2006, but that doesn’t mean it’s a joke of a world this April Fools’ Day and the folks behind Pluto TV want to make that clear.

On April 1, the free Pluto TV streaming service will host a “sit-in” to revisit the Pluto planethood debate while also celebrating the 10th anniversary of the live TV streaming service. The event, dubbed “Pluto TV’s Rally for Pluto! Make Pluto A Planet!,” runs from 11:30 a.m. to 1 p.m. Pacific Time at the University of California Los Angeles’ Bruin Plaza. And if you can’t make it in person, you can sign a Change.org petition for Pluto’s planethood to make your voice heard.
