Buchholz, Germany: Multiple planetoids — 26 June 1819
Astronomer J.W. Pastorff (1767-1838) observed what he thought was a “comet” close to
the Sun, but Olbers pointed out it could not have been a comet. The same day, Gruithuisen (observing from Holland) reported three unknown bodies crossing the disk of the Sun, ”… viz, one near the middle of the Sun, and two small ones without nebulosity near the western limb.” It is notable that this observation, initially published in Reverend Webb’s well-known astronomy handbooks, has been deleted from recent editions!
