1991 BA Asteroid

1991 BA is an asteroid, a large rock that orbits the Sun mainly between the orbits of Mars and Jupiter. They tend to be an irregular shaped but Ceres asteroid is known to be spherical in shape but because it doesn't clear its path round the Sun, it is only a dwarf planet. A close approach will occur on 2023 Jan 18 when it will get to within 0.0207 A.U. Its orbit takes 3.06 years to travel round the Sun.

The absolute magnitude of the object is 28.7 which is the brightness of the object. A higher absolute magnitude means that the object is faint whereas a very low number means it is very bright.

The Semi-Major Axis of the orbit is 2.105, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which 1991 BA orbits in relation to the orbital plane is 2.1 degrees. The orbital eccentricity is 0.667, it is the degree at which 1991 BA orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Path of 1991 BA Orbit

If the white lines are above, then the path of the object is under the ecliptic. If the white lines are below, the path is above the ecliptic. This refers to the Inclination of the object. The image was created using N.A.S.A. Solar System Dynamics.
