What makes Comet 3I/ATLAS interstellar?

Comet 3I/ATLAS is considered interstellar because it originated outside of our solar system. Unlike typical comets, which form within our solar system, interstellar comets enter from the vast reaches of space, providing unique chemical and physical data.

How is the Hubble Telescope involved with Comet 3I/ATLAS?

The Hubble Space Telescope is observing Comet 3I/ATLAS to gather data on its speed, path, and composition. This information is crucial for understanding its behavior and refining its trajectory within our solar system.

What role does the Psyche mission play?

Originally aimed at observing a metal-rich asteroid, the Psyche mission has expanded to include tracking 3I/ATLAS. By doing so, it helps NASA compare interstellar and solar system objects, enhancing both scientific knowledge and planetary defense strategies.
