The star's Henry Draper (HD) ID in the Hipparcos (Hip for short) star catalogue is 31398. Converting from HipId to HDId was carried out using the table provided by Richard Dibon-Smith site.
The star's spectral class is "K3IIvar" which is a bright giant. The star is located in the constellation of Auriga. Hassaleh lies at a distance of 512.03 lights years or put it another way 156 parsecs from our solar system. The stars temperature has been calculated at about 3,700 - 5,200 K based on the Class Type and lookup at Wikipedia-Stellar ClassificationThe star's colour is orange based on the spectral type and the table at the wikipedia page.
Hassaleh has a right ascension of 04h 56m 59.62 which is the equivalent to the Earth longitude reading but for space. Longitude is how far west or east a location is.
Hassaleh has a declination of +33°09`58.1 degrees which is the equivalent to the latitude reading on Earth but for space. Latitude is how far north or south a location is relative to the Equator. Zero degrees latitude on Earth is the Greenwich Maritime Line or Prime Meridian.
