Overview

Betulia is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Betulia as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

Betulia orbits the sun every 1,189 days (3.26 years), coming as close as 1.13 AU and reaching as far as 3.27 AU from the sun. Betulia is about 5.8 kilometers in diameter, making it larger than most asteroids, comparable in size to the San Francisco Bay.

The rotation of Betulia has been observed. It completes a rotation on its axis every 6.13 days.

Betulia's spectral type C (Tholen) / (SMASSII) indicates that it is likely to contain nickel, iron, cobalt, water, nitrogen, and ammonia.

Close Approaches

Betulia's orbit is 0.14 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

Betulia has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 21, 2142 26,122,678 27.902
May 25, 2155 22,556,870 28.181
May 26, 2168 25,821,673 28.336

Images and Observations

Betulia's orbit is determined by observations dating back to May 22, 1950. It was last officially observed on July 17, 2018. The IAU Minor Planet Center records 1,192 observations used to determine its orbit.

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