NGC 6210, sometimes also known as the Turtle Nebula, [4] is a planetary nebula located in the constellation Hercules, approximately 5.4 ± 1.3 kly from the Sun. [2] It is positioned about 38° above the galactic plane at a vertical distance of about 3.3 kilolight-years (1 kpc) and thus has little extinction from intervening interstellar dust. [5]

Theta Herculis is a single, [11] variable star in the northern constellation of Hercules. This object is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 3.851. [2] Based upon parallax measurements, it is located around 750 light years away from the Sun.
Delta Herculis (δ Herculis, abbreviated Delta Her, δ Her) is a multiple star system in the constellation of Hercules. Its light produces to us apparent magnitude 3.12, as such the third-brightest star in the large, fairly dim constellation.
To see it, first locate the Hercules constellation, then look to the west for the Northern Crown, a horseshoe-shaped curve of stars. “[The Northern Crown] ...
