Asteroid (7150) McKellar

In 1941, Andrew McKellar (1910–1960) measured the temperature of interstellar space as about 2.7 Kelvin, based of the rotational spectrum of the cyanogen molecule. This radiation temperature arises from the cosmic primeval fireball and is one of the most fundamental and revealing cosmic parameters.
