This is an #exoplanet (β pic b) orbiting its host #star.

The #planet is directly observed over 17 years by various instruments with different size of coronographs (the black disk in the #instrument occulting the star).

From 2004 to 2010 and from 2016 to 2018, the planet is too close to the star such as it is also behind the #coronograph.

β pic b is a young (12Myr) massive planet (~10Mjup) with period of ~20 yr 🪐
