1607 Mavis, provisional designation 1950 RA, is an eccentric, stony asteroid from the inner regions of the asteroid belt, about 12 kilometers in diameter. It was discovered by South African astronomer Ernest Johnson at Union Observatory in Johannesburg on 3 September 1950.[8]
The asteroid orbits the Sun at a distance of 1.8–3.3 AU once every 4 years and 1 month (1,487 days). Its orbit shows an eccentricity of 0.31 and is tilted by 9 degrees to the plane of the ecliptic. It has a rotation period of 6.1 hours.[6][7] The stony S-type asteroid's albedo has been determined by the Akari and WISE missions to amount to 0.189±0.007 and 0.2487±0.0428, respectively, while the Lightcurve Database project derived a much higher value of 0.36.[3]
It was named in honor of the Mavis Bruwer, wife of astronomer Jacobus Albertus Bruwer, astronomer at the observatory in Johannesburg, after whom the minor planet 1811 Bruwer was named.[2]
