Atira asteroid
In great part because of the search methods used to look for asteroids, there are currently no known asteroids with orbits contained within Venus (Q = 0.728 AU) or Mercury's (Q = 0.467 AU, e.g. vulcanoids). As of January 2019, the asteroid with the smallest known aphelion is , with an aphelion of 0.773 AU.
