Asteroid 3200 Phaethon

Altitude: -16.8°   Azimuth: 337.8°   Direction: North-North-West

Asteroid 3200 Phaethon was discovered on October 11, 1983, by Simon Green and John K. Davies using data from the Infrared Astronomical Satellite (IRAS). Its name comes from Greek mythology, where Phaethon was the son of the sun god Helios. Phaethon is an Apollo asteroid, meaning it has a highly eccentric orbit that crosses the Earth's orbit, and it is the parent body of the Geminid meteor shower. It has a diameter of about 5.8 kilometers and an elongated, irregular shape. The surface of Phaethon is believed to be heavily cratered and covered in a layer of dust, and it may have a composition similar to some types of meteorites. Its orbit brings it closer to the Sun than any other named asteroid, with a perihelion of just 0.14 astronomical units (AU) and an aphelion of 2.4 AU. Phaethon has an orbital period of 1.4 years and rotates once on its axis every 3.6 hours.

Asteroid 3200 Phaethon is currently in the constellation of Pisces, at a distance of 400,468,375 kilometers from Earth.

Asteroid 3200 Phaethon Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 3200 Phaethon, 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.
