Comet Encke - Wikipedia
Comet Encke / ˈɛŋki /, or Encke's Comet (official designation: 2P/Encke), is a periodic comet that completes an orbit of the Sun once every 3.3 years. (This is the shortest period of a reasonably bright comet; the faint main-belt comet 311P/PanSTARRS has a period of 3.2 years.)

2024年10月13日 · Encke’s Comet, faint comet having the shortest orbital period (about 3.3 years) of any known; it was also only the second comet (after Halley’s) to have its period established. The comet was first observed in 1786 by French astronomer Pierre Méchain. In 1819 German astronomer Johann Franz Encke.
Encke – old faithful comet, shortest orbit, between Jupiter and sun
Encke is a periodic comet with a very short run of only 3 years. It comes within Earths view (though not always visible to the naked eye) in such a short period because unlike most comets, Encke only goes as far out as Jupiter.

2004年3月31日 · Comet Encke is closest to Earth in mid-November, passing our planet at 0.26 astronomical unit (39 million kilometers). Since its discovery more than two centuries ago there have been just nine returns, including this one, in which the comet has come within 0.3 a.u. of us.
Comet 2P/Encke - Space Reference
2P/Encke is a mid-sized comet whose orbit brings it closer to the sun than Jupiter. NASA JPL has classified 2P/Encke as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2023年9月11日 · Comet 2P/Encke, the parent comet of the Taurid meteor stream, has one of the shortest orbital period of any bright comet, taking just 3.3 years to go around the Sun.
Comet Encke returns! - Australian Geographic
Comet Encke has the shortest orbital period of any known comet within our solar system. It’s not as famous as Halley’s, but Comet 2P/Encke circles the Sun once every 3.3 years. During its 2023 return it will be seen best at dawn in early September, above the north-eastern horizon.
