NASA’s Lucy spacecraft could unravel the mystery of how the solar system formed
The Lucy spacecraft is a NASA mission that will launch in October 2021 and will explore the Trojan asteroids, a group of asteroids that orbit the sun in two swarms ahead of and behind Jupiter. The Trojans are thought to be remnants of the early solar system, and their study could help us to understand how the solar system formed.
The Lucy spacecraft will visit six Trojan asteroids over the course of its 12-year mission. The spacecraft will study the asteroids’ composition, shape, and surface features, and it will also collect data on the asteroids’ environment. The data collected by Lucy will help us to better understand the formation and evolution of the solar system.
The Trojan asteroids
The Trojan asteroids are a group of asteroids that orbit the sun in two swarms, one ahead of and one behind Jupiter. They are thought to be remnants of the early solar system, and their study could help us to understand how the solar system formed.
The Trojans are located at the Lagrange points L4 and L5, which are two points in space where the gravitational pull of the sun and Jupiter cancel each other out. This allows the Trojans to orbit the sun in a stable formation.
There are an estimated million Trojan asteroids, ranging in size from a few kilometers to over 100 kilometers across. The largest Trojan asteroid is Patroclus, which is about 110 kilometers across.
The Trojans are thought to have formed in the same region of the solar system as Jupiter, and they were likely scattered to their current locations by the gravitational pull of Jupiter. The Trojans are relatively undisturbed by other planets, so they are thought to be a good record of the early solar system.
The Lucy spacecraft will visit six Trojan asteroids over the course of its 12-year mission. The spacecraft will study the asteroids’ composition, shape, and surface features, and it will also collect data on the asteroids’ environment. The data collected by Lucy will help us to better understand the formation and evolution of the solar system.

The Lucy spacecraft will visit six Trojan asteroids over the course of its 12-year mission. The spacecraft will study the asteroids’ composition, shape, and surface features, and it will also collect data on the asteroids’ environment. The data collected by Lucy could reveal a wealth of information about the early solar system, including⁚
- The composition of the early solar system⁚ The Trojans are thought to be made up of the same material that formed the planets, so studying their composition could help us to understand the composition of the early solar system.
- The formation of the planets⁚ The Trojans are thought to have formed in the same region of the solar system as the planets, so studying their formation could help us to understand how the planets formed.
- The evolution of the solar system⁚ The Trojans have been orbiting the sun for billions of years, so studying them could help us to understand how the solar system has evolved over time.
In addition to these broad scientific goals, the Lucy mission could also answer some specific questions about the Trojan asteroids, such as⁚
- Are the Trojans made up of the same material as the planets?
