Edmund Halley na English scientist wey don live over 200years ago. E study di observations of comets wey other scientists don make. Di orbit of one particular comet na very difficult mathematical problem. E no fit figure am out. Neither fit other scientists wey dey deal with such problems.

However, Halley get one friend wey dem dey call Isaac Newton. Wey be say na brilliant mathematician. Newton think say e don already figure am out. E tell Halley say di orbit of a comet get di shape of an ellipse.

Now Halley begin work. E figure out di orbits of some of di comets wey scientists don observe. E make one surprising discovery. Di comets wey don appear for di years 1531, 1607 and 1682 all get di same orbit. Yet their appearances don dey 75 to 76 years apart.

Dis one dey very strange to Halley. Three different comets dey follow di same orbit. Di more Halley think about am, di more e think say dem no be three different comets, as people think. E decide say dem just see di same comet three times. Di comet don go away and e don come back again.

E be one astonishing idea! Halley feel sure say make e predict wetin go happen for di future. E decide say dis comet go appear for di year 1758. Dem get 53 years to go before Halley's prediction fit be tested.

For 1758 di comet appear for di sky. Halley no see am, because e don die some years before. Ever since then, dem don dey call di comet Halley's comet, in e honor.
