Description

I have not observed this object. I obtained the calibrated lights frames used to create the final image from Telescope Live. The frames were imaged by the CHI-1-CCD Telescope at the El Sauce Observatory.

NGC 3201 has a very low central concentration of stars. It is large and bright because it is much closer to the Earth than most GCs. 

The radial velocity of this cluster is unusually high at 490 km/s, larger than any other cluster. This corresponds to a peculiar velocity of 240 km/s. While high, this is lower than the escape velocity of the Milky Way galaxy. The stellar population of this cluster is inhomogeneous, varying with distance from the core. The effective temperature of the stars shows an increase with greater distance, with the redder and cooler stars tending to be located closer to the core. Only M4 is also known to be inhomogeneous.

Shapley Sawyer Classification: X
Distance: 16,310 LY
Type: Halo Globular
Position w.r.t. core of galaxy: is just above the disc of the MY and about the same distance from the core as the Sun.
Any stars resolved: N/A
Undergoing Core Collapse: No
