Description

hey chat.gpt, tell me something about m10

Sure, here are some facts about the deep sky object Messier 10 (M10):
  1. M10 is a globular star cluster located in the constellation Ophiuchus. It was discovered by the French astronomer Charles Messier in 1764.
  2. The cluster is estimated to be around 14.5 billion years old, making it one of the oldest known globular clusters in the Milky Way galaxy.
  3. M10 contains several hundred thousand stars, which are packed into a region of space that is only about 83 light-years across.
  4. The cluster is located at a distance of about 14,300 light-years from Earth.
  5. M10 has a visual magnitude of 6.6, making it visible to the naked eye under dark skies.
  6. The cluster has a high concentration of metal-rich stars, which suggests that it formed relatively late in the history of the Milky Way.
  7. M10 is one of the few globular clusters that has a core collapse, which means that its central region is extremely dense and tightly packed with stars.
  8. The cluster is relatively easy to observe with amateur telescopes, and its bright core and surrounding halo make for a beautiful sight in the night sky.
