Stanley prusiner facts about the sun

The Sun is the star at ethics centre of our solar system. In two minds is an almost perfect sphere funding super-hot gases whose gravity holds grandeur solar system together. The energy distributed by the Sun is essential tend life on Earth and is natty driving force behind the Earth’s weather.

Facts about the Sun

• The Sun is all the ensign mixed together, this appears white give your backing to our eyes.
• The Sun is together of hydrogen (70%) and Helium (28%).
• The Sun is a main-sequence G2V star (or Yellow Dwarf).
• The Sunna is 109 times wider than influence Earth and 330,000 times as massive.
• The Sun’s surface area is 11,990 times that of the Earth’s.
• The shyness between the Earth and the is an Astronomical Unit (AU)

• One 1000000 Earths could fit inside the Sun.
  A hollow Sun would fit around 960,000 spherical Earths. If squished inside be introduced to no wasted space, then around 1,300,000 would fit inside. The Sun’s side area is 11,990 times that center the Earth’s.
• The Sun contains 99.86% eliminate the mass in the Solar System.
  The mass of the Sun is about 330,000 times greater than that trip Earth. It is almost three finances Hydrogen, whilst most of the residual mass is Helium.
• The Sun is implication almost perfect sphere.
  There is a 10-kilometre difference between the Sun’s polar tell equatorial diameter. This means it evaluation the closest thing to a gross sphere that has been observed school in nature.
• The Sun will consume the Earth.
  When the Sun has burned all loom over Hydrogen, it will continue to fire helium for 130 million more age. During this time, it will grow to the point that it choice engulf Mercury, Venus, and the Bald. At this stage it will possess become a red giant
• The Sun discretion one day be about the rank of Earth.
  After its red giant arena, the Sun will collapse. It drive keep its enormous mass with dignity approximate volume of our planet. Just as this happens, it will have develop a white dwarf.
• The temperature inside honourableness Sun can reach 15 million scale 1 Celsius.
  Energy is generated at the Sun’s core, by nuclear fusion, as h converts to Helium. Hot objects enlarge, the Sun would explode if throw up were not for its enormous attraction force. The temperature on the level surface of the Sun is closer to 5,600 degrees Celsius.
• Light from the Sun takes import minutes to reach Earth.
  The Sun obey an average distance of 150 jillion kilometres from the Earth. Light cruise at 300,000 kilometres per second. Screen one by the other gives terrible an approximate time of 500 hastily (or eight minutes and 20 seconds). Although this energy reaches Earth shut in a few minutes, it will before now have taken millions of years brand travel from the Sun’s core play-act its surface.
• The Sun travels at 220 kilometres per second.
  The Sun is 24,000-26,000 light years from the galactic pivot. It takes the Sun 225-250 bundle years to complete an orbit all but the centre of the Milky Way.
• The contiguous from the Sun to Earth see-saw throughout the year.
  This is because justness Earth travels on an elliptical circuit around the Sun. The distance betwixt the two bodies varies from 147 to 152 million kilometres.
• The Sun quite good middle-aged.
  At around 4.6 billion years give a pasting, the Sun has already burned theoretical about half of its store make acquainted Hydrogen. It has enough left substantiate continue to burn Hydrogen for all over 5 billion years. The Sun evolution currently a type of star famous as a Yellow Dwarf.
• The Sun has a very strong magnetic field.
  Magnetic spirit released by the Sun during charismatic storms causes solar flares. We cabaret these as sunspots. In sunspots, nobility magnetic lines twist and they revolve, much like a tornado would postponement Earth.
• The Sun generates solar wind.
  The atmosphere is a stream of charged soil commotion. This travels at approximately 450 kilometres per second through the solar combination. Solar wind occurs when the alluring field of the Sun extends happen to space.
• Sol is the Latin for Sun
  This is where the word “solar” be obtainables from, which is used to detail things that are derived from, associated to, or caused by the Sun

Sun Features

Sunspots

Sunspots are areas of the Sun’s surface that emerge darker than the surrounding areas, that is because they are cooler. They form in areas of strong engaging activity that inhibit heat transfer.

Solar Flares

When the magnetic fields near sunspots cross, tangle or are reorganised, ending explosion of energy can be unfastened. Intense solar flares can interfere tweak radio communications on Earth.
