The first condition is that it must have a mass falling within a certain range. It contains more than Explore More The Seamstress And The Secrets Of The Argonaut Shell Known since Aristotle, no one understood the argonaut octopus—until a 19th-century seamstress turned naturalist took it upon herself to solve its mysteries. There was some discussion of naming the planet after Le Verrier, but ultimately Neptune, which has a vivid blue color, got its name from the Roman god of the sea. If you were to fill a hollow Sun with spherical Earths, somewhere around , would fit inside. But eventually it will run out of hydrogen fuel. The Sun has a powerful magnetic field. Neptune, the planet farthest from the Sun it makes a solar revolution once every years , was first seen by telescope in by German astronomer Johann Gottfried Galle, using the mathematical calculations of French astronomer Urbain Le Verrier and British astronomer John Couch Adams. The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol. This is called a solar eclipse; if the alignment is slighly imperfect then the Moon covers only part of the Sun's disk and the event is called a partial eclipse. One day the Sun will consume the Earth. At the center of the core the Sun's density is more than times that of water.

His astronomical pedigree was impeccable: He was the son of the Titan Hyperion and the Titaness Theia. Visit Website Two other planets, Uranus and Neptune, were discovered after the telescope was invented in the early s.

history of the name of the sun

Though debated, this range is generally accepted to be between approximately 1. Considering the sheer size of the Sun, there is only a 10 km difference in its polar and equatorial diameters — this makes it the closest thing to a perfect sphere observed in nature.

Temperatures inside the Sun can reach 15 million degrees Celsius. Light travels atkm per second so dividing one by the other gives you seconds — eight minutes and twenty seconds.

Who named the sun

At the center of the core the Sun's density is more than times that of water. Similar effects are seen in the gas planets. Helios was also the brother of Selene, the goddess of the Moon, and Eos, the goddess of the dawn. The differential rotation extends considerably down into the interior of the Sun but the core of the Sun rotates as a solid body. The reason they appear dark is due to their temperature being much lower than surrounding areas. Its magnetosphere also known as the heliosphere extends well beyond Pluto. In terms of size, the Sun has a diameter of roughly 1. The moon, on the other hand, was typically referred to with the feminine pronoun during this period. Sunspots are caused by complicated and not very well understood interactions with the Sun's magnetic field. This changes slowly over time as the Sun converts hydrogen to helium in its core. And you can see the solar corona. During the solar maximum, however, the solar wind moves at an intermediate speed. The Romans bestowed the names of gods and goddesses on the five planets that could be seen in the night sky with the naked eye. So people often travel half way around the world just to see a total solar eclipse. The first condition is that it must have a mass falling within a certain range.

This is called a solar eclipse; if the alignment is slighly imperfect then the Moon covers only part of the Sun's disk and the event is called a partial eclipse. In terms of size, the Sun has a diameter of roughly 1.

Origin of the word sun

It is a main sequence star with surface temperatures between 5, and 5, degrees celsius 9, and 10, degrees fahrenheit. The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol. Once the Sun has completed its red giant phase, it will collapse. However, if compared to the most common type of star in the universe, the red dwarf, the Sun is quite a bit larger. Some estimates for stars similar to the Sun in the Milky Way galaxy alone are as high as 7 billion. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. Visit Website Two other planets, Uranus and Neptune, were discovered after the telescope was invented in the early s. While our Sun does not have an official scientific name, it does have another common name: Sol. Elizabeth Nix Roman mythology is to thank for the monikers of most of the eight planets in the solar system. What is the Sun?

An elected member of the National Academy of Medicine, he is editor-in-chief of the Milbank Quarterly and a Guggenheim fellow. It is often said that the Sun is an "ordinary" star. The highly rarefied region above the chromosphere, called the corona, extends millions of kilometers into space but is visible only during a total solar eclipse left.

The Sun is about 4.

The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol. What we have also discovered is that although other planets and bodies in the Solar System may not possess life, the Sun is just as influential to them.
