Asteroid ‘Dinkinesh’/Lucy spacecraft

The National Aeronautics and Space Administration’s (NASA) Lucy spacecraft is on an epic 6-billion-kilometre-long journey to study the Jupiter Trojan asteroids.

Discovery - It was discovered in 1999 by the LINEAR survey, and recently identified as a potential fly-by target for the Lucy mission.
Orbit - It orbits the Sun in the main belt of asteroids between the orbits of Mars and Jupiter.
Width - It is less than 1 kilometre wide.
Composition - Dinkinesh is an S-type asteroid, i.e., it is composed mainly of silicates and some metal.
Instrument - The observations were made by Lucy’s high-resolution camera, the Lucy Long Range Reconnaissance Imager ( L’LORRI instrument ).
Dinkinesh will be the first asteroid that Lucy will visit on its 12-year-long journey.

Lucy Spacecraft

Lucy mission was launched on October, 2021.
Agency – NASA, U.S.
Aim - To observe the Jupiter Trojan asteroids (huge group of small bodies that orbit the Sun in two “swarms.”)
Lucy will first fly by Dinkinesh and another asteroid in the main belt called Donaldjohnson in 2025.
WISE - NASA’s Wide-field Infrared Survey Explorer (WISE) is supporting the flyby.
It provides updated estimates of the asteroid’s size and albedo – a measurement of surface reflectivity that could help scientists better understand the nature of some near-Earth objects.
