2324 Janice, provisional designation 1978 VS4, is a dark background

rotation period of 23.2 hours.[4]

Orbit and classification

Based on osculating Keplerian

602), a very large family of carbonaceous asteroids, named after 24 Themis.[4]

When applying the

background population (according to Nesvorný),[3] as well as a core member of the Themis family (according to Milani and Knežević).[5]

It orbits the Sun in the

semi-major axis of 3.08 AU). Its orbit has an eccentricity of 0.18 and an inclination of 0° with respect to the ecliptic.[2] The body's observation arc begins with its first observation as A911 MC at Lowell Observatory in June 1911, more than 67 years prior to its official discovery observation at Palomar.[1]

Physical characteristics

Janice is a presumed carbonaceous

602).[4]

Rotation period

In October 2010, a rotational

U=2-).[11] As of 2018, no secure period has been obtained.[4]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.038 and 0.093.[6][7][8][9][10][12]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.08 and calculates a diameter of 23.55 kilometers based on an absolute magnitude of 11.5.[4]
