Length of Exoplanet Day Measured for First Time
VLT measures the spin of Beta Pictoris b
Exoplanet Beta Pictoris b orbits the naked-eye star Beta Pictoris, which lies about 63 light-years from Earth in the southern constellation of Pictor (The Painter’s Easel). This planet was discovered nearly six years ago and was one of the first exoplanets to be directly imaged. It orbits its host star at a distance of only eight times the Earth-Sun distance - making it the closest exoplanet to its star ever to be directly imaged.
