Abstract
7984 Marius is a minor planet located in the asteroid main-belt region between Mars and Jupiter, which formed about 4.5 billion years ago when the planets emerged from the dense gas and dust disk around the Sun. The asteroid has an orbit with a semi-major axis of 2.63 AU, an eccentricity of 0.20, and an inclination of 9.1°, with an orbital period of 4.27 years. Light curves indicate a rotation period of 3.54 h and a slightly elongated shape. A radiometric analysis of infrared observations shows that 7984 Marius has a low albedo of about 6% and a diameter of approximately 10.5 km. The low albedo points toward a possible carbonaceous surface composition. Its absolute magnitude is 13.6 mag, and the object reaches a maximum brightness of about 16.4 mag during favorable oppositions.

Official observatory code: 046 (see also MPC 5615).

“SM” in the provisional designation of 7984 (1980 SM) was probably the reason for linking this object to Simon Marius. The details for the selection process and the origin of the citation text are not known.

The albedo determines how much sunlight is reflected and how much is absorbed by the surface of a given object. An albedo of 10% means that 10% of the sunlight is reflected.
