2010 AB78


is a dark asteroid on an eccentric orbit, classified as near-Earth object of the Amor group. It was first observed by the Wide-field Infrared Survey Explorer on 12 January 2010. The asteroid measures approximately 1.7 kilometers in diameter and has a low albedo of 0.03, which is rather typical for carbonaceous asteroids.

First ''WISE'' discovery

is expected to become the first of the many thousands of discoveries to be accredited to the WISE space telescope. However, the official discoverer will only be defined upon the asteroid's numbering.
The first observation of by WISE was on January 12, 2010, being observed again the next day. The Mauna Kea Observatory observed it the days 18 and 19 of January, allowing the Minor Planet Center to publish a circular on January 22 confirming the discovery.

Orbit

orbits the Sun at a distance of 1.0–3.5 AU once every 3 years and 5 months. Its orbit has an eccentricity of 0.55 and an inclination of 33° with respect to the ecliptic. Due to its eccentric orbit it is also a Mars-crosser. has the lowest possible orbital uncertainty, which suggests that it will be numbered in the near future.

Close approaches

This near-Earth asteroid has a minimum orbital intersection distance with Earth of, which corresponds to 80.2 lunar distances. It does not make any notable close approaches to Earth within the next hundred years.

Physical characteristics

According to the survey carried out by the NEOWISE mission of NASA's discovering WISE observatory, measures 1.671 kilometers in diameter and its surface has an albedo of 0.030. Objects known for such low albedos are the carbonaceous C, D and P-type asteroids.
As of 2018, no lightcurve has been obtained. The body's rotation period, shape and pole remain unknown.

Numbering and naming

As of 2018, this minor planet has not been named or numbered.
