Asteroid 13 Egeria
Asteroid 13 Egeria is a relatively large asteroid with a diameter of approximately 214 kilometers. It was discovered on November 2, 1850, by Italian astronomer Annibale de Gasparis and named after the Roman goddess Egeria, who was associated with wisdom and prophecy. The asteroid orbits the Sun between Mars and Jupiter, with a semi-major axis of approximately 2.66 astronomical units (AU) and an orbital period of about 4.45 years. Egeria's orbit is moderately eccentric and inclined compared to other asteroids in the main belt. It rotates relatively slowly, with a rotation period of about 14.1 hours. Egeria is also classified as a C-type asteroid, indicating that its surface is likely rich in carbonaceous materials. It is relatively bright and can be observed with a small telescope under favorable conditions.
Asteroid 13 Egeria is currently in the constellation of Pisces Austrinus.
The current Right Ascension of Asteroid 13 Egeria is 22h 35m 20s and the Declination is -29° 50’ 14” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current magnitude of Asteroid 13 Egeria is 12.09 (JPL).

Asteroid 13 Egeria Distance from Earth
The distance of Asteroid 13 Egeria from Earth is currently 356,980,926 kilometers, equivalent to 2.386270 Astronomical Units. Light takes 19 minutes and 50.7602 seconds to travel from Asteroid 13 Egeria and arrive to us.
The following chart shows the distance of Asteroid 13 Egeria from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 13 Egeria from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 13 Egeria to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 13 Egeria to Earth happens on Fri Jan 14 1955 at a distance of 1.428381 Astronomical Units, or 213,682,816 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 13 Egeria Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 13 Egeria, 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.
