Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the island of Manhattan (3.61 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Smirnova is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Smirnova as potentially hazardous because its orbit does not bring it close to Earth.
Smirnova orbits the sun every 1,530 days (4.19 years), coming as close as 1.79 AU and reaching as far as 3.40 AU from the sun. Smirnova is about 3.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of Smirnova has been observed. It completes a rotation on its axis every 39.98 hours.
No Close Approaches
Smirnova's orbit is 0.79 AU from Earth's orbit at its closest point. This means that there is a 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
Smirnova's orbit is determined by observations dating back to Aug. 30, 1971. It was last officially observed on May 2, 2023. The IAU Minor Planet Center records 2,142 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
