The volume of a Bok globule one light year across [19] [20] 8.47 × 10 47: One cubic light-year ~1.7 × 10 48: Volume of the Oort Cloud, assuming a radius of 50 000 AU ~1.6 × 10 49: Volume of the Dumbbell Nebula: 2.94 × 10 49: One cubic parsec: 4.4 × 10 50: Approximate volume of the Bubble Nebula (NGC 7635) (assuming a radius of 5 light ...
The siriometer is an obsolete astronomical measure equal to one million astronomical units, i.e., one million times the average distance between the Sun and Earth. [13] This distance is equal to about 15.8 light-years, 149.6 Pm, or 4.8 parsecs, and is about twice the distance from Earth to the star Sirius. [14]
The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration. Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.
The largest unit for expressing distances across space at that time was the astronomical unit, equal to the radius of the Earth's orbit at 150 million kilometres (93 million miles). In those terms, trigonometric calculations based on 61 Cygni's parallax of 0.314 arcseconds, showed the distance to the star to be 660 000 astronomical units (9.9 ...
Orion took the snapshot around its maximum distance from Earth of 268,563 miles. That's the farthest any human-oriented spacecraft has traveled, beating even Apollo 13's record of 248,655 miles ...
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
1.2 Ym – 127 million light-years – distance to the closest observed gamma ray burst GRB 980425; 1.3 Ym – 137 million light-years – distance to the Centaurus Cluster of galaxies, the nearest large supercluster; 1.9 Ym – 201 million light-years – diameter of the Local Supercluster; 2.17 Ym – 1 light-galactic-years – 230 million ...
The tradition of thousands of people crowding to watch a shimmering ball be lowered in Times Square began in 1907, though the first New Year's Eve celebration in the iconic intersection began in 1904.
