At its average distance, light travels from the Sun's horizon to Earth's horizon in about 8 minutes and 20 seconds, [37] while light from the closest points of the Sun and Earth takes about two seconds less. The energy of this sunlight supports almost all life [c] on Earth by photosynthesis, [38] and drives Earth's climate and weather. [39]
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 ...
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 ...
The Earth's inhabited side is always opposite to the Central Fire, rendering it invisible to people. So, the Earth rotates around itself synchronously with a daily orbit around that Central Fire, while the Sun revolves it yearly in a higher orbit. That way, the inhabited side of Earth faces the Sun once every 24 hours.
The properly-scaled, basket-ball-sized model is 1.3 miles (2.14 km) from the model Sun which is located at the museum, graphically illustrating the immense empty space in the Solar System. The objects in such large models do not move.
"A new study of 56,000 sun-like stars reveals that other stars like ours may experience powerful superflares about once per century, shedding light on the potential for rare but extreme solar ...
Earth orbits the Sun, making Earth the third-closest planet to the Sun and part of the inner Solar System. Earth's average orbital distance is about 150 million km (93 million mi), which is the basis for the astronomical unit (AU) and is equal to roughly 8.3 light minutes or 380 times Earth's distance to the Moon .
