468 Lina is a main belt asteroid. It was discovered by Max Wolf on January 18, 1901 at Heidelberg. Its provisional name was 1901 FZ. This asteroid was named Lina after the housemaid of Max Wolf's family.[3] It is a core member of the Themis family of asteroids.

Photometric observations of 468 Lina at the Altimira Observatory in California during 2006 showed a rotation period of 16.33 ± 0.02 hours and a brightness variation of 0.15 in magnitude. The light curve showed an unusual triple peak shape.[2]

Analysis of infrared observations from the Spitzer Space Telescope give a diameter of 59.7 ± 0.5 km, albedo of 0.058, and absolute magnitude 9.83. The values are significantly different from the earlier results obtained with IRAS, which gave a diameter of 69.34 ± 2.5 km and albedo of 0.043 ± 0.003. 468 Lina shows an emissivity plateau in the wavelength range of 9 to 12 μm, which is indicative of silicates.[1]
