4183 Cuno, provisional designation 1959 LM, is an eccentric, rare-type asteroid, classified as near-Earth object and potentially hazardous asteroid. It belongs to the group of Apollo asteroids and measures approximately 5 kilometers in diameter. It was discovered by German astronomer Cuno Hoffmeister at Boyden Observatory in Bloemfontein, South Africa, on 5 June 1959.
The asteroid orbits the Sun at a distance of 0.7–3.2 AU once every 2 years and 9 months (1,019 days). Its orbit has an eccentricity of 0.63 and an inclination of 7° with respect to the ecliptic. As an anomaly, the asteroid's observation arc begins with the first used observation made at Palomar Observatory in 1986, or 27 years after its discovery. It is also a Mars- and Venus-crosser. The asteroid has an Earth minimum orbital intersection distance of 0.0285 AU (4,260,000 km) and approaches the Earth to within 40 million kilometers six times in the 21st century. On 20 May 2012, it made its closest Earth approach at a distance of 0.122 AU (18,000,000 km). It will not make a closer approach until 2093 when it will pass Earth at 0.084 AU (13,000,000 km).
The stony S-type asteroid, with its reflective surface composed of a mixture different silicates, nickel and iron, is also classified as a rare Q-type asteroid by the NASA IRTF telescope, the 1-meter JKT on La Palma, and Pan-STARRS' large-scale magnitude survey. On the SMASS taxonomic scheme, it is a Sq-subtype, a transitional group between the S and Q types.
