Asteroid with shortest orbital period discovered Jan 3

Discovered on 2019 January 3 by the Zwicky Transient Survey, a 576 megapixel, 36-cm square camera on the 48-inch Schmidt telescope on Palomar Mountain. This object, measuring around 1 km across, orbits the Sun in just 165 days. See the diagram of its orbit (courtesy of ESA NEOCC). The black dot marks the position of the asteroid on January 4. Its orbit is strongly tilted some 47 degrees to the ecliptic.
