* Profile

It was discovered in 1979 and observed again in 1985. But it has not been observed since that.

Kazuo Kinoshita's calculation revealed that it passed close by Jupiter in 1979 and the perihelion distance reduced from 1.8 A.U. down to 1.6 A.U. However, it passed close by Jupiter again in 1988, and the perihelion distance increased up to 2.2 A.U.

It came to approach close to the sun and brighten up to 17 mag temporarily in 1979 and 1985, so it was observed. However, now that it went far away again, it reached only to 21 mag at best.
