For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

| 5574 Seagrave | Discovered 1984 Mar. 20 by Z. Vavrova at Klet. |
| Frank Evans Seagrave (1860-1934) was an American amateur astronomer, who observed the Sun, variable stars, novae, comets and minor planets from his private observatory. He was a prodigious computer of orbits of minor planets and comets, including the 1910 return of 1P/Halley. |
