The centre of the Milky Way is about 26 000 light-years away. [35] [36] 1 × 10 5 ly: The Milky Way is about 100 000 light-years across. 1.65 × 10 5 ly: R136a1, in the Large Magellanic Cloud, the most luminous star known at 8.7 million times the luminosity of the Sun, has an apparent magnitude 12.77, just brighter than 3C 273. 10 6: 2.5 × 10 6 ly
Lengths are given in divine years (a.k.a. celestial or Deva years), where a divine year lasts for 360 solar (human) years. A chatur-yuga lasts for 4.32 million solar (12,000 divine) years with 1,728,000 years of Krita-yuga , 1,296,000 years of Treta-yuga , 864,000 years of Dvapara-yuga , and 432,000 years of Kali-yuga .
Distance light travels in one day — Light-year: 63 241 — Distance light travels in one Julian year (365.25 days) — Oort cloud: 75 000: ± 25 000: Distance of the outer limit of Oort cloud from the Sun (estimated, corresponds to 1.2 light-years) — Parsec: 206 265 — One parsec. The parsec is defined in terms of the astronomical unit, is ...

A light-year is the distance light travels in one Julian year, around 9461 billion kilometres, 5879 billion miles, or 0.3066 parsecs. In round figures, a light year is nearly 10 trillion kilometres or nearly 6 trillion miles. Proxima Centauri, the closest star to Earth after the Sun, is around 4.2 light-years away. [89]
13 Ym – 1.37 billion light-years – length of the South Pole Wall; 13 Ym – 1.38 billion light-years – length of the Sloan Great Wall; 18 Ym – redshift 0.16 – 1.9 billion light-years – distance to the quasar 3C 273 (light travel distance) 30.8568 Ym – 3.2616 billion light-years – 1 gigaparsec
These promises would eventually become the forerunners to the New Year's resolutions seen today. Years later, Julius Caesar would go on to establish Jan. 1 as the beginning of the New Year in ...
One galactic year is approximately 225 million Earth years. [2] The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its trajectory around the Galactic Center, [ 3 ] a speed at which an object could circumnavigate the Earth's equator in 2 minutes and 54 seconds; that speed corresponds to ...
