These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
File:Sun, Earth size comparison labeled.jpg The sun and the earth. Size comparison only. The Earth and Sun are approximately 150 gigameters (1AU) or around 107 suns apart. File:Sun, Earth size comparison.jpg Without text Not for voting. The Earth and moon, shown to scale including correct relative distance. An amazing picture of the sun and the ...
Size comparison of the Sun, all the planets of the Solar System and some larger stars. The Sun is 1.4 million kilometers (4.643 light-seconds ) wide, about 109 times wider than Earth, or four times the Lunar distance , and contains 99.86% of all Solar System mass .
Thus, the angular diameter of Earth's orbit around the Sun as viewed from a distance of 1 pc is 2″, as 1 AU is the mean radius of Earth's orbit. The angular diameter of the Sun, from a distance of one light-year, is 0.03″, and that of Earth 0.0003″. The angular diameter 0.03″ of the Sun given above is approximately the same as that of a ...
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [96] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [102] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [103]
The diurnal parallax of the Sun was accurately measured during the transits of Venus in 1761 and 1769, [5] yielding a value of 9″ (9 arcseconds, compared to the present value of 8.794 148 ″). From the value of the diurnal parallax, one can determine the distance to the Sun from the geometry of Earth. [6] [7]
Evolution of the solar luminosity, radius and effective temperature compared to the present-day Sun. After Ribas (2009) [3] The uncrewed SOHO spacecraft was used to measure the radius of the Sun by timing transits of Mercury across the surface during 2003 and 2006. The result was a measured radius of 696,342 ± 65 kilometres (432,687 ± 40 miles).
English: Comparison of angular diameter of the Sun, Moon and planets with the International Space Station (as seen from the surface of the Earth), the 20/20 row of the Snellen eye chart at the proper viewing distance and typical human visual acuity. The dotted circles represent the minimum angular size (when the celestial bodies are farthest ...
