It takes 1916.53 days to complete an orbit around the Sun. Mortensen’s absolute magnitude is 12.2, it has a diameter of 14.481km and it’s albedo is estimated at 0.141.
At Mortensen we like the idea of looking at things with distance, getting close and moving away without prefixed orbits and with galactic eccentricity. The name Mortensen is a homage to this small rock, to Inger Mortensen and to all of our aunts.
