1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2; 1 cm – edge of a cube of volume 1 mL; 1 cm – length of a coffee bean; 1 cm – approximate width of average fingernail; 1.2 cm – length of a bee; 1.2 cm – diameter of a die; 1.5 cm – length of a very large mosquito; 1.6 cm – length of a Jaragua Sphaero, a very small reptile
Tau Ceti's habitable zone—the locations where liquid water could be present on an Earth-sized planet—spans a radius of 0.55–1.16 AU, where 1 AU is the average distance from the Earth to the Sun. [66] Primitive life on Tau Ceti's planets may reveal itself through an analysis of atmospheric composition via spectroscopy, if the composition ...
The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [7] [8] [9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
The aircraft was climbing, using rated military power, with 10–15 degrees of flaps to get on top of the overcast, when it impacted, skipped about 60 feet (18 m), and slid another 20 feet (6.1 m) before partially burning, coming to rest almost at the crest of the ridge. [114]
[15] [121] The suspect apparently carried the PETN onto the plane in a 6-inch (15 cm)-long [19] soft plastic container, possibly a condom, attached to his underwear. Much of the container was lost in the fire. [ 123 ]
The Pea galaxies, also known as Green Peas (GPs), are compact oxygen-rich emission line galaxies that were discovered at redshift between z = 0.112 and 0.360. [1] These low-mass galaxies have an upper size limit generally no bigger than 16,300 light-years (5,000 pc) across, and typically they reside in environments less than two-thirds the density of normal galaxy environments.

Post-glacial rebound raises the land by a bit less than 1 cm (0.4 in) per year in the north and east, extending the coast. A circle enclosing the same area as Denmark would be 234 kilometres (145 miles) in diameter with a circumference of 736 km (457 mi) (land area only: 232.33 km (144.36 mi) and 730 km (454 mi) respectively).
