6312 Robheinlein (1990 RH4) is a main-belt asteroid discovered on September 14, 1990, by H. E. Holt at Palomar.

This asteroid is named after Robert Anson Heinlein, the Dean of Science Fiction, author of the mainstream literary classic Stranger in a Strange Land, and Science Fiction novels Starship Troopers and The Moon is a Harsh Mistress.

Heinlein helped narrate The Moon Landing with Walter Cronkite on CBS in 1969, was involved in the planning of the Star Wars Defense program in the 1980s, contributed the words Waldo and Grok to the English language, and popularized the phrases Space Marine, TANSTAAFL, and Pay it Forward.
