NGC 1701, also known as the Trekkie Galaxy,[1] is a large spiral galaxy located in the constellation Caelum. Its speed relative to the cosmic microwave background is 5,836 ± 24 km/s, which corresponds to a Hubble distance of 86.1 ± 6.0 Mpc (∼281 million ly).[2] It was discovered by the British astronomer John Herschel in 1834.[2][3][4]
