1803 H. Brougham in Edinb. Rev. Jan. 430 Why may we not coin such a phrase as Planetoid?

1803 W. Herschel in Philos. Trans. (Royal Soc.) 93 339 It is not in the least material whether we call them asteroids, as I have proposed; or planetoids, as an eminent astronomer, in a letter to me, suggested.

1899 Daily News 17 Jan. 7/3 The new ‘planetoid’ was discovered by Herr Witt, of the Urania Observatory of Berlin.

1927 Sci. Monthly Jan. 17 Most of the planetoids have very highly eccentric orbits.

1950 C. Bonestell & W. Ley Conquest of Space iv. 140 Now the so-called ‘asteroids’, or better planetoids, were no longer hunted down patiently, they were caught in a photographic net.

1995 Times 8 June 16/3 Planets form when left-over chunks of material around the protostar collide to make planetoids, which in turn merge to become planets.

1856 Times 5 Aug. 7/1 I was the first person who called the attention of astronomers to the apparently planetoid and periodical nature of the meteors.

1862 H. Holland Ess. 280 (note) Nearly seventy now (1862) stand in our catalogues..the heathen mythology has been invoked in vain to furnish names for this planetoid throng.

1960 Science 1 Jan. 32/1 A single successful planetoid experiment would increase the absolute accuracy with which interplanetary distances are known from a figure well below that realizable in laboratory measurements to a figure well above it.

1991 C. A. Ronan Nat. Hist. Universe 102/2 Planetoid material that did not coalesce into larger units formed the asteroids or minor planets.
