Where can I find Messier M3?
Messier 3 can be found halfway from the bright star Arcturus in Boötes constellation to Cor Caroli in Canes Venatici. It lies about 6 degrees north-northeast of Beta Comae Berenices, near the border between the constellations Canes Venatici and Boötes.
How do you find the M3 cluster?
Finding M3
- Start by finding the Big Dipper in the Northern summer sky.
- Next, find the bright yellow star Arcturus, high in the sky toward the West.
- The easy way to find Arcturus is to trace the arc of the Big Dipper’s handle, and imagine that line continuing to Arcturus.
- Next, find Cor Caroli.

What makes Arcturus special?
Arcturus Is a Powerhouse Red Giant Star It shines roughly 113 times brighter, despite Arcturus only being about 1.5 times bigger than our sun. Arcturus also releases roughly 215 times more heat than the sun, proof that it is generating a ton of energy despite its size.
What is the Messier 3 cluster?
Messier 3. Messier 3 (M3 or NGC 5272) is a globular cluster of stars in the northern constellation of Canes Venatici. It was discovered on May 3, 1764, and was the first Messier object to be discovered by Charles Messier himself.
What can Messier 3 tell us about the Milky Way?
Messier 3 is quite isolated as it is 31.6 kly (9.7 kpc) above the Galactic plane and roughly 38.8 kly (11.9 kpc) from the center of the Milky Way. It contains 274 known variable stars, by far the most found in any globular cluster. These include 133 RR Lyrae variables, of which about a third display the Blazhko effect of long-period modulation.
Can you see Messier 3 with a 4 inch telescope?
With a visual magnitude of 6.2, Messier 3 is difficult (but not impossible) to see without binoculars even in good viewing conditions, but the cluster appears fully defined in a moderate-sized telescope. A 4-inch telescope will reveal the bright core without resolving individual stars.
Who was the first person to observe Messier 3?
William Herschel was the first to resolve Messier 3 into individual stars and recognise it as a cluster in 1784. He observed M3 using a 20-foot long reflector and described it as “one of the globular clusters; very brilliant and beautiful.
