Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Connecticut (147.49 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

Flora is a average-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Flora as potentially hazardous because its orbit does not bring it close to Earth.

Flora orbits the sun every 1,193 days (3.27 years), coming as close as 1.86 AU and reaching as far as 2.55 AU from the sun. Flora is about 147.5 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Connecticut.

The rotation of Flora has been observed. It completes a rotation on its axis every 12.87 days.

No Close Approaches

Flora's orbit is 0.87 AU from Earth's orbit at its closest point. This means that there is an very wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

Flora's orbit is determined by observations dating back to Oct. 27, 1847. It was last officially observed on May 13, 2019. The IAU Minor Planet Center records 2,744 observations used to determine its orbit.

Scientists have been able to determine this object's shape.
