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.

Distance from Earth
The distance of asteroid 8 Flora from Earth is currently
The following graph shows the distance of asteroid 8 Flora from Earth as a function of time. In the chart the distance is measured in Astronomical Units and the data is sampled with an interval of 1 day.
Note: The values in this chart may not be entirely accurate around the time of closest approach for objects passing very close to Earth at high speed (e.g., Near-Earth Objects).
The value of the distance of 8 Flora from Earth is also available as a real time updated value in the live position tracker.
Closest Approach to Earth
In the period between January 1, 1900 and December 31, 2099, the closest approach of asteroid 8 Flora to Earth happened on Monday 30 October 1922 at a distance of 0.873221 Astronomical Units, or 130,632,051 kilometers:
Note: the values for the closest approach are computed with a sampling interval of 1 day.
Light Curve
The following chart shows the light curve of asteroid 8 Flora, i.e., its apparent magnitude as a function of time. The curve is calculated using the latest ephemerides provided by JPL Horizons. The magnitude data is sampled with the interval of 2 days. Because of this sampling, inaccuracies may occur for objects that have large variations of brightness over a few days. For comets, large discrepancies can arise between the calculated brightness and the observations due to their highly dynamic, and not always precisely predictable, behavior.
