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 Solar System. [26]
Brian Cury, CEO and founder of EarthCam, Inc., launched EarthCam.com in 1996 to build a network of webcams offering views of destinations throughout the world. In 1999 it was claimed 20 people per day were adding their webcams to the website. [3] By 2006 the website was a Webby Award Winner in the Tourism category. [4]
The core of the Sun is considered to extend from the center to about 0.2 of the solar radius (139,000 km; 86,000 mi). [1] It is the hottest part of the Sun and of the Solar System . It has a density of 150,000 kg/m 3 (150 g/cm 3 ) at the center, and a temperature of 15 million kelvins (15 million degrees Celsius; 27 million degrees Fahrenheit).
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
The objective behind the construction of these observatories was to assemble astronomical data and to accurately predict the movement of the planets, moon, sun, etc. in the solar system. It was a one of a kind in its time when it was built. By the year 1867, when India was under the British Raj, the observatory had undergone considerable decay. [3]
It is a webcam located on Kala Patthar, a mountain in Nepal located in front of Everest, in the Himalayas Himalaya, at an elevation of 5,675 metres (18,619 ft).The webcam capture video footage of the summit of Mount Everest and is the highest webcam in the world. [1]
The Sun's oscillation modes represent a discrete set of observations that are sensitive to its continuous structure. This allows scientists to formulate inverse problems for the Sun's interior structure and dynamics. Given a reference model of the Sun, the differences between its mode frequencies and those of the Sun, if small, are weighted ...
