Waist-to-height ratio: the average ratio for US college competitive swimmers is 0.424 (women) and 0.428 (men); the ratios for a (US) normally healthy man or woman is 0.46–0.53 and 0.45–0.49 respectively; the ratio ranges beyond 0.63 for morbidly obese individuals. [15]
The Hill sphere (gravitational sphere of influence) of the Earth is about 1,500,000 kilometers (0.01 AU) in radius, or approximately four times the average distance to the Moon. [12] [nb 2] This is the maximal distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets. Objects orbiting the Earth must ...
A woman who is 36–24–36 (91.5–61–91.5) at 5 ft 3 in (1.60 m) tall looks different from a woman who is 36–24–36 at 5 ft 8 in (1.73 m) tall. Since the latter woman's figure has greater distance between measuring points, she will likely appear thinner than her former counterpart, again, even though they share the same measurements.
According to their developed formula, this would mean the waist of a male adult who is 5'10" should be no larger than 35 inches. Similarly, a 5'4" woman's waist should measure 32 inches.
The Sun, taking along the whole Solar System, orbits the galaxy's center of mass at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph), [167] taking about 220–250 million Earth years to complete a revolution (a Galactic year), [168] having done so about 20 times since the Sun's formation.
Solstice day arcs as viewed from 70° latitude. At local noon the winter Sun culminates at −3.44°, and the summer Sun at 43.44°. Said another way, during the winter the Sun does not rise above the horizon, it is the polar night. There will be still a strong twilight though. At local midnight the summer Sun culminates at 3.44°.
Where the waist is convex rather than concave, as in pregnancy and obesity, the waist may be measured at a vertical level 1 inch above the navel. [3] Strictly, the waist circumference is measured at a level midway between the lowest palpable rib and the iliac crest, [4] respectively typically 60% and 64% of total height. [5]
The Sun follows the solar circle (eccentricity e < 0.1) at a speed of about 255 km/s in a clockwise direction when viewed from the galactic north pole at a radius of ≈ 8.34 kpc [4] about the center of the galaxy near Sgr A*, and has only a slight motion, towards the solar apex, relative to the LSR.
