Asteroid 192 Nausikaa was discovered on February 17, 1879 by Austrian astronomer Johann Palisa. It is a relatively large and dark main-belt asteroid, with an estimated diameter of about 106 kilometers. The name Nausikaa comes from Greek mythology. Nausikaa was a princess who helped the hero Odysseus when he was shipwrecked on her island. Nausikaa's orbital period around the Sun is about 4.3 years, and its average distance from the Sun is approximately 2.8 astronomical units (AU), or about 420 million kilometers. The asteroid's orbit is slightly inclined to the plane of the ecliptic, and it has a moderate eccentricity of about 0.18.

Asteroid 192 Nausikaa is in the constellation of Libra, at a distance of 389,343,703.0 kilometers from Earth. The current Right Ascension is 14h 44m 37s and the Declination is -21° 27’ 58” (apparent coordinates). The magnitude of Asteroid 192 Nausikaa is 12.96 (data provided by JPL Horizons).

Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 192 Nausikaa, 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.
