The comet Nishimura, which was only discovered in August, will soon be slingshotted around the sun and back out toward the edge of the solar system where it will remain for centuries.
An extremely bright comet that was only discovered last month is set to make its closest approach to Earth today as it falls rapidly toward the sun. The icy object, known as"Comet Nishimura," will soon be slingshotted around our star and back into the outer reaches of the solar system, where it will remain for the next four centuries.
Comet Nishimura's unusual orbit initially hinted it might be an interstellar comet that originated from outside the solar system, such as 'Oumuamua and Comet 2I/Borisov. If this was the case, this appearance would have likely been its first and only journey into the inner solar system. However, further observations have shown its orbit around the sun likely lasts around 430 years, according to NASA via AP News.
The comet's coma — the cloud of gas and dust that surrounds its solid core — gives off a green light because it contains molecules of dicarbon, which emit green light when they are broken down by sunlight, according to Science magazine.
