| Proper Name | Finlay | | Designation | 15P | | Orbital inclination to the Ecliptic | 6.80° | | Orbital Period | 6 years, 208 days | | Distance from the Sun | Semi-Major Axis: 524,736,000 km (3.51 AU)
Perihelion: 148,473,000 km (0.99 AU)
Aphelion: 900,999,000 km (6.02 AU) | | Eccentricity | 0.7171 | | Notes | A short-period comet whose path through the Solar System carries it out past the orbit of Jupiter, and then inward to a distance from the Sun comparable to that of Earth, over a period of less than seven years. Its orbit is notable as intersecting closely with Earth's, so that it can theoretically approach the planet as closely as 1.3 million kilometres. In practice, its closest likely approach in the near future will be in the year 2060, when it will pass within about five million kilometres of Earth. |
