Asteroid 4 Vesta

Altitude: 6.0°   Azimuth: 59.7°   Direction: East-North-East

4 Vesta is a large asteroid located in the asteroid belt between Mars and Jupiter. It was discovered on March 29, 1807 by German astronomer Heinrich Wilhelm Olbers and is one of the largest asteroids in the solar system, with a diameter of approximately 525 kilometers. Vesta has a relatively bright surface and is thought to be one of the few remaining protoplanets from the early solar system that has not undergone significant alteration since its formation. It has a differentiated interior, with a rocky crust, a mantle, and a metallic core. Vesta has a rotation period of about 5.34 hours and an orbital period of 3.63 Earth years. It has been observed by ground-based telescopes, as well as by the Dawn spacecraft, which orbited the asteroid from 2011 to 2012. The observations have revealed insights into its geology, composition, and history, including evidence of volcanic activity, impact craters, and a unique set of surface features known as "Vestoids", which are fragments believed to have been ejected from Vesta's surface by impacts.

Asteroid 4 Vesta is currently in the constellation of Taurus, at a distance of 305,421,708 kilometers from Earth.

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 4 Vesta from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Asteroid 4 Vesta to Earth

Between 1 January 1600 and 30 December 2499, the closest approach of Asteroid 4 Vesta to Earth happens on Thu Jun 23 2439 at a distance of 1.131542 Astronomical Units, or 169,276,274 kilometers:

Asteroid 4 Vesta Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 4 Vesta, 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.
