An Exoplanet Orbiting 51 Eridani

This brief (~4 second) video shows a Jupiter-sized exoplanet orbiting 51 Eridani. The star’s planetary system is face-on as seen from Earth, giving us a bird’s-eye view of the planet’s motion as it orbits about 18 billion km from the star. The video was assembled from five images taken over four years with the Gemini South Telescope in Chile. The Gemini Planet Imager blocks out most of the star’s light so that the much fainter and smaller exoplanet can be seen.
