Asteroid 79 Eurynome was discovered on September 14, 1863 by James Craig Watson at the Detroit Observatory in Michigan. It is believed to be a member of the Themis family of asteroids located in the outer part of the main asteroid belt. Eurynome has a diameter of approximately 114 km and completes one orbit around the Sun every 5.5 years. Its name comes from Greek mythology, where Eurynome was a daughter of Oceanus and Tethys, and was known for her grace and beauty. Little is known about Eurynome's surface and composition, but it is believed to be a primitive C-type asteroid.

Asteroid 79 Eurynome is in the constellation of Gemini, at a distance of 205,464,715.0 kilometers from Earth. The current Right Ascension is 07h 14m 59s and the Declination is +14° 45’ 18” (apparent coordinates). The magnitude of Asteroid 79 Eurynome is 11.15 (data provided by JPL Horizons).

Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 79 Eurynome, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
