Comet Kohoutek is a long-period comet; its previous apparition was about 150,000 years ago, and its next apparition will be in about 75,000 years. At its apparition in 1973, it had a hyperbolic trajectory (e > 1) due to gravitational perturbations from giant planets. Due to its path, scientists theorized that Kohoutek was an Oort-cloud object. As such, it was believed that this was the comet's first visit to the inner Solar System, which would result in a spectacular display of outgassing. Infrared and visual telescopic study have led many scientists to conclude, in retrospect, that Kohoutek is actually an Edgeworth/Kuiper-belt object, which would account for its apparent rocky makeup and lack of outgassing.
Before its close approach, Kohoutek was promoted by the media as the "comet of the century". However, Kohoutek's display was considered a let-down, possibly due to partial disintegration when the comet closely approached the Sun prior to its Earth flyby. Since this was probably the comet's first visit to the inner Solar System, it would have still contained large amounts of frozen volatiles since its formation. Although it failed to brighten to the levels expected, it was still a naked-eye object. Its greatest visual magnitude was −3, when it was at perihelion, 0.14 AU (21,000,000 km; 13,000,000 mi) from the Sun. Its orbital inclination is 14.3°. Its best viewing was in the night sky after perihelion, when it had dimmed to fourth magnitude. The comet also sported a tail up to 25° long, along with an anti-tail.
Kohoutek was observed by the crews of Skylab 4 and Soyuz 13; it thus became the first comet to be observed by a manned spacecraft, for Apollo 13's planned observations of the prominent naked-eye Comet Bennett had been aborted by the Moon-bound craft's oxygen-tank explosion.
C/1973 E1 should not be confused with the periodic comet 75D/Kohoutek, which can also be called "Comet Kohoutek". In addition, there are another two long-period comets, C/1969 O1-A (a.k.a. 1970 III, 1969b), and C/1973 D1 (a.k.a. 1973 VII, 1973e) also discovered by Luboš Kohoutek.
Because Comet Kohoutek fell far short of expectations, its name became synonymous with spectacular disappointment. However, it was bright compared with the most usual comets, and put on a respectable show in the evenings shortly after perihelion.
In 1973, David Berg, founder of the Children of God, predicted that Comet Kohoutek foretold a colossal doomsday event in the United States in January 1974.[unreliable source?] Children of God members distributed Berg's message of doom across the country. The majority of U.S.-based members then fled in anticipation to existing communes, or formed new ones, around the world.
In popular cultureEdit
Comet Kohoutek inspired numerous musicians and other artists:
- Madeline L'Engle's poem "The Risk of Birth, Christmas, 1973" refers to "a comet slashing the sky to warn/that time runs out and the sun burns late".

R.E.M. had previously announced their intentions to never play the song live again in 1997, but a live recording of the track (along with a large portion of their early years catalog) was recorded in 2007 and released later on the album Live at the Olympia in 2009.

- The English singer-songwriter Peter Hammill began recording his 1974 album In Camera in December 1973, the same month that the comet attained perihelion. One of the songs on the album is entitled "The Comet, The Course, The Tail"; Hammill confirmed via his Twitter account in 2017, that Kohoutek provided inspiration for the song.
- In The Mary Tyler Moore Show episode "Ted Baxter Meets Walter Cronkite" (season 4, episode 21), Mary is nominated for a Teddy Award but loses to a production titled "A Comet Named Kohoutek".
