Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
The parsec is defined in terms of the astronomical unit, is used to measure distances beyond the scope of the Solar System and is about 3.26 light-years: 1 pc = 1 au/tan(1″) [60] [61] Proxima Centauri: 268 000: ± 126 Distance to the nearest star to the Solar System — Galactic Centre of the Milky Way: 1 700 000 000 —
695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, 109 times the radius of the Earth, and 1/215th of an astronomical unit, the approximate distance between Earth and the Sun. The solar radius to either pole and that to the equator differ slightly due to the Sun's rotation, which induces an oblateness in ...

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. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of ...
The U.S. was expected to add a record 32 gigawatts of new solar capacity by the end of 2023, a 52% increase from 2022, according to a September report from the Solar Energy Industries Association ...
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]
