... Maximum angle on the sky occurs when the angle from Callisto to Jupiter to Earth is 90 degrees. From basic geometry, the angle between the Earth–Callisto and Earth–Jupiter sides of this right triangle is: θ = arctan(dCJ /dJE ) where dCJ is the distance from Callisto to Jupiter and dJE is the distanc ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
