Japanese astronomer Masayuki Iwamoto discovered a new comet in late 2018. It’s a fast-moving comet that will be closest to Earth on February 12, 2019, at around 3:10 p.m. EST (20:10 UTC; translate to your time zone). The celestial visitor will safely pass by Earth at some 28 million miles (45 million km). The comet has been designated C/2018 Y1 (Iwamoto).
This comet is fast! Comet C/2018 Y1 (Iwamoto) is traveling through space at the amazing speed of 147,948 miles per hour (238,099 km/h) or 66 km per second, relative to Earth.
The best nights for observing the comet with optical aid should be on February 12 and 13. It will not be visible to the eye alone. But observers report it is now visible in binoculars.
The orbit of comet C/2018 Y1 (Iwamoto) is so elliptical (elongated), that calculations indicate it takes around 1,371.3 years to return.
As you see this astronomical object with your own eyes (using binoculars or a small telescope), it will be amazing to realize that humans might see this comet again around year 3390.
Amateur astronomers have been catching wonderful images of this comet for some time. If you get a good image, please submit it to EarthSky Community Photos. Good luck!
