The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [3] The distance, measured by the Gaia mission, is 655±13 light-years. [4]

NGC 2685 (also known as the Helix Galaxy) is a lenticular and polar ring Seyfert Type 2 galaxy in the constellation Ursa Major. Its velocity with respect to the cosmic microwave background is 1003 ± 9 km/s, which corresponds to a Hubble distance of 48.2 ± 3.4 Mly (14.79 ± 1.05 Mpc ). [ 1 ]
Oppose The individual pictures are great but I don't think it is useful in this format. File:Earth's Location in the Universe SMALLER (JPEG).jpg has a more useful 4x2 format and a perfectly adequate size for both screen and printing up to A3 format. Using the Interactive large-image-viewer (flash-based) on my Firefox browser gives the most ...
NGC 6543 is 4.4 minutes of arc from the current position of the north ecliptic pole, less than 1 ⁄ 10 of the 45 arcminutes between Polaris and the current location of the Earth's northern axis of rotation. It is a convenient and accurate marker for the axis of rotation of the Earth's ecliptic, around which the celestial North Pole rotates.
Knowledge of the location of Earth has been shaped by 400 years of telescopic observations, and has expanded radically since the start of the 20th century. Initially, Earth was believed to be the center of the Universe , which consisted only of those planets visible with the naked eye and an outlying sphere of fixed stars . [ 1 ]
Earth's location in the Universe. Universe – all of time and space and its contents.. Observable universe – spherical region of the Universe comprising all matter that may be observed from Earth at the present time, because light and other signals from these objects have had time to reach Earth since the beginning of the cosmological expansion.
