Solar System Identification
Object D
orbits - sun
distance from Sun (star) AU's - 20.1
shape of object - sphere
diameter of object (km) - 51118
natural satellites - 7
orbit eccentricity (how elliptical) - 0.04
orbit inclination (degrees) - 1
orbital zone cleared of objects (similar size or smaller) - yes
if you can identify this object in the solar system with a great explanation of why then i might mark you brainliest and give you free points!
