| Smallest orbit | KOI-55.01 | KOI-55 | 0.006 AU | |
| Smallest orbit around binary star | Kepler-47b | Kepler-47AB | ≃0.3 AU | |
| Smallest ratio of semi-major axis of a planet orbit to binary star orbit | Kepler-16b | Kepler-16AB | 3.14 ± 0.01 | Ratio of planet orbit to binary star orbit (by semi-major axis) |
| Largest orbit around binary star | DT Virginis c | DT Virginis | 1168 AU | Star system is also known as Ross 458 AB. The planet was eventually confirmed to be below deuterium burning limit but its formation origin is unknown. |

Famous quotes containing the word orbit:
“The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!”
—E.T.A.W. (Ernst Theodor Amadeus Wilhelm)
