Asteroid 8 Flora

Altitude: 19.4°   Azimuth: 209.2°   Direction: South-South-West

Asteroid 8 Flora has an orbital period of 3.27 years and a semi-major axis of approximately 2.2 astronomical units (AU), which places it in the main asteroid belt between the orbits of Mars and Jupiter. It was discovered on October 18, 1847, by astronomer John Russell Hind, and is named after the Roman goddess of flowers and gardens. Flora has a diameter of approximately 136 kilometers and is irregularly shaped, with a rotation period of about 8.67 hours. Flora is also the largest member of the Flora family of asteroids, a group of objects that share similar orbital and physical characteristics. The Flora family is thought to have formed from the collisional breakup of a larger asteroid, possibly due to a collision with a planetesimal or a disruptive event in the early solar system. The study of Flora and its family of asteroids has provided important insights into the history and evolution of the main asteroid belt and the formation of the solar system.

Asteroid 8 Flora is currently in the constellation of Aquarius.

The current Right Ascension of Asteroid 8 Flora is 22h 51m 30s and the Declination is -14° 40’ 39” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current magnitude of Asteroid 8 Flora is 10.13 (JPL).

Asteroid 8 Flora Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 8 Flora, 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.
