Neowise

Definition

Neowise is a comet, designated C/2020 F3, that was discovered by the NEOWISE mission on March 27, 2020. This comet gained significant attention due to its bright appearance and visible tail, becoming one of the brightest comets to be seen in the Northern Hemisphere in decades. It originated from the outer reaches of the solar system, showcasing the dynamic processes involved in the movement and evolution of comets, which are crucial to understanding our solar system's formation.

5 Must Know Facts For Your Next Test

1. Neowise was initially discovered using infrared observations by the NEOWISE spacecraft, which is designed to find and study near-Earth objects.
2. The comet reached perihelion, its closest approach to the Sun, on July 3, 2020, after which it became visible to observers on Earth.
3. Neowise exhibited a prominent double tail, consisting of a dust tail and an ion tail, which are characteristic features of comets when they approach the Sun.
4. It provided a unique opportunity for astronomers and enthusiasts alike to observe a comet with the naked eye during its peak visibility in July 2020.
5. The comet's path takes it back into the outer solar system, where it will not return for thousands of years, making its appearance a rare event.
