Byblis

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. state of Delaware (76.13 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Byblis orbits the sun every 2,050 days (5.61 years), coming as close as 2.58 AU and reaching as far as 3.74 AU from the sun. Byblis is about 76.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Byblis has been observed. It completes a rotation on its axis every 5.22 hours.

Byblis's spectral type None (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Byblis's orbit is 1.57 AU from Earth's orbit at its closest point. This means that there is an extremely 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

Byblis's orbit is determined by observations dating back to July 10, 1879. It was last officially observed on March 28, 2023. The IAU Minor Planet Center records 3,908 observations used to determine its orbit.
