Upper limits to the masses of objects in the solar comet cloud

OSTI ID:5432087
The lack of a large steady stream of long-period comets with semi-major axes less than 2 x 10/sup 4/ AU rules out the sun having a companion more massive than about 0.01 M/sub solar/ with a semi-major axis less than about 1 x 10/sup 4/ AU. Any companion with a semi-major axis between 1 x 10/sup 4/ AU and 5 x 10/sup 4/ AU has more than a 50% probability of having entered the planetary system during the lifetime of the Solar System. The lack of apparent damage to the planetary system rules out any companion more massive than about 0.02 M/sub solar/ with a semi-major axis less than about 5 x 10/sup 4/ AU.
