Asteroid 2 Pallas

Altitude: 46.5°   Azimuth: 204.2°   Direction: South-South-West

2 Pallas is a large asteroid located in the asteroid belt between Mars and Jupiter. It was discovered by German astronomer Heinrich Wilhelm Olbers on March 28, 1802 and is one of the largest asteroids in the solar system, with a diameter of approximately 544 kilometers. It has a highly irregular shape, with a large impact crater on one side that suggests it may have experienced a significant collision in its past. 2 Pallas has a relatively high density compared to other asteroids, indicating that it may be composed of a significant amount of metal or have a differentiated interior. It has a rotation period of about 7.8 hours and an orbital period of 4.6 Earth years. Because of its irregular shape and complex surface features, 2 Pallas is considered a challenging target for spacecraft missions. However, observations from Earth-based telescopes and the Hubble Space Telescope have provided valuable insights into its geology, composition, and history.

Asteroid 2 Pallas is currently in the constellation of Hercules, at a distance of 370,228,518 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 2 Pallas from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Asteroid 2 Pallas to Earth

Between 1 January 1600 and 30 December 2499, the closest approach of Asteroid 2 Pallas to Earth happens on Sat Feb 16 1608 at a distance of 1.193832 Astronomical Units, or 178,594,670 kilometers:

Asteroid 2 Pallas Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2 Pallas, 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.
