Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the city of Houston (36.82 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Solvejg is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Solvejg as potentially hazardous because its orbit does not bring it close to Earth.
Solvejg orbits the sun every 1,990 days (5.45 years), coming as close as 2.51 AU and reaching as far as 3.69 AU from the sun. Solvejg is about 36.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.
The rotation of Solvejg has been observed. It completes a rotation on its axis every 19.33 hours.
Solvejg's spectral type BC: (Tholen) / B (SMASSII) indicates that it is likely to contain hydrogen, nitrogen, ammonia, and iron.
No Close Approaches
Solvejg's orbit is 1.49 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
Solvejg's orbit is determined by observations dating back to March 18, 1926. It was last officially observed on May 5, 2023. The IAU Minor Planet Center records 4,510 observations used to determine its orbit.
