1850 Kohoutek, provisional designation 1942 EN, is an asteroid from the inner regions of the asteroid belt, discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 23 March 1942.[3] Since the discovery was made in the second half of March, the letter "E" in the provisional designation is erroneous. It should have been "F", but the initially incorrect assignment has persisted (also see Provisional designation in astronomy § Minor planets).[citation needed]
The asteroid orbits the Sun at a distance of 2.0–2.5 AU once every 3.38 years (1,233 days). Its orbit shows an eccentricity of 0.13 and is inclined by 4 degrees to the plane of the ecliptic. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty of 0 and an observation arc that spans over a time period of more than 70 years.[1]
It is named in honor of the Czech astronomer, Luboš Kohoutek (b. 1935), former staff member of the Hamburg-Bergedorf Observatory and prolific observer and discoverer of 75 asteroids as well as numerous comets, most notably 75D/Kohoutek, 76P/West–Kohoutek–Ikemura, and the long-period Comet Kohoutek. He has also contributed in the fields of planetary nebulae and emission-line stars.[2]
