Measuring large distances
... The easiest way to measure the distance to a planet or star is through a method called parallax. • The parallax method (or triangulation, as it’s sometimes known) depends on having a baseline of known length. • A distant object is sighted accurately from both ends of the baseline. The angles to the ...

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.
