What is HIP 100256

At 262 light years in the Dolphin, this white A-type star glows at magnitude 5.96. Its light set out around 1764, when James Watt was patenting his improved steam engine in Glasgow. The small constellation of the Dolphin, which the Greek imagination dedicated to the rescuer of Arion, hosts modest points like this one, where the cold white of A-type stars mingles with the dust of the summer Milky Way.
