I-comet yokuqala umntu owaziyo ukuba izakubuyela, yaye yayiye.
UEdmond Halley waqonda ngo1705 ukuba iinkwenkwezi ezibonakala ngo1531, 1607 no1682 zaziyizinto ezifanayo kwaye waqikelela ukubuyela kwayo ngo1758. Yaye yayiyi komethi yokuqala eyaziwayo njengexesha elijikelezayo.
I-orbit yayo ihlala kwindawo ejikelezayo (e ≈ 0.97) kwaye ihamba ngasemva. Idlulele ilanga ngowe-1986, xa iESA Giotto yenqwelo-moya yawela phantsi kwengcambu yayo, kwaye izakubuyela ngowe-2061.
