The article investigates whether ancient Greek astronomer Hipparchus observed the planet Uranus. More specifically, the author argues that an object depicted in the constellation Virgo in the "Almagest" star catalog of astronomer Claudius Ptolemy, called Virgo 17, was likely the planet Uranus and observed by Hipparchus in 128 BCE.
