      You’re right! The article explains the comet idea is only a few years old, and new data confirms it’s an asteroid, not a comet.

      I think comets have predictable paths for long periods of time so they show up again and again, like Haley’s comet

What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth’s surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more…
