5786 Talos (1991 RC) is an Apollo asteroid discovered on September 3, 1991, by R. H. McNaught at Siding Spring, it has a very small perihelion distance; only two other named asteroids have one less than 0.2 AU, 1566 Icarus and 3200 Phaethon, 3200 Phaethon, provisional designation 1983 TB , is an Apollo asteroid with an unusual orbit that brings it closer to what, than any other named asteroid?

3581 Alvarez 3581 Alvarez (1985 HC) is a Mars-crossing asteroid discovered on April 23, 1985, by Shoemaker, C. and Shoemaker, E. at Palomar. Based upon lightcurve data, it has a synodic rotation period of  hours with an amplitude variation of in magnitude. With a diameter of ~14 km, it is one of the largest Mars-crossing asteroids. However, due to the high inclination of its orbit, it never actually passes through the orbit of Mars since at perihelion it is well away from the plane of Mars' orbit. The asteroid is named after planetary scientist Walter Alvarez and his Nobel-prize winning father, physicist Luis Alvarez.
