NASA’s Lucy is on its way to study Jupiter’s Trojan asteroids but passed by our planet for a “hello again” and a boost. It was the first of three flybys of Earth, which are necessary to send it on the right trajectory, and it took place on October 15.

Lucy is named after the Australopithecus afarensis remains discovered in Hadar, located in the African country. Lucy will be studying multiple objects in the Trojans – asteroids considered fossils of the early Solar System.
The photo of the Moon and Earth was taken two days before the flyby and it shows just how far the Moon is from Earth. It was snapped from 1.4 million kilometers (890,000 miles).
The next flyby will be on December 13, 2024. It will then visit asteroid Donaldjohanson in the Asteroid main belt, as well as the asteroids Eurybates, Polymetes, Leucus, and Orus, which precede Jupiter in its orbit. Lucy will then fly by Earth again on December 26, 2030, before flying to binary asteroids Patroclus-Menoetius in the groups of asteroids that follow Jupiter.
