Right Ascension and Declination

 

Imagine that the Earth is at the centre of a huge sphere in space. Then imagine that all the objects we see in the night sky are held at points on the sphere. This imaginary sphere is known as the celestial sphere. We can measure locations on the sphere using coordinates calledright ascension (RA)and declination (Dec).

Yesterday I learned about Comet Nishimura - 1st spotted by a backyard astronomer Aug 13 2023 (!)

It's path is very unusual- parabolic vs elliptical & will slingshot back out of the solar system, never to return.

Viewing:

Just before dawn, in the East around the Leo constellation
