Sun

The Dominicus is the star at the centre of our solar system. It is an almost perfect sphere of super-hot gases whose gravity holds the solar system together. The free energy produced past the Sun is essential for life on Earth and is a driving force behind the Earth's weather.

Age: iv.6 Billion Years
Type: Yellow Dwarf (G2V)
Diameter: one,392,684 km
Equatorial Circumference: four,370,005.six km
Mass: i.99 × 10^thirty kg (333,060 Earths)
Surface Temperature: 5,500 °C

Facts about the Sun

  • The Sun is all the colours mixed together, this appears white to our optics.
  • The Sun is composed of hydrogen (70%) and Helium (28%).
  • The Dominicus is a main-sequence G2V star (or Xanthous Dwarf).
  • The Lord's day is 109 times wider than the World and 330,000 times every bit massive.
  • The Sun's area is eleven,990 times that of the Earth'due south.
  • The altitude between the Earth and the Dominicus is an Astronomical Unit (AU)
  • One million Earths could fit within the Sunday.
    A hollow Dominicus would fit around 960,000 spherical Earths. If squished within with no wasted space, then around 1,300,000 would fit inside. The Sun'south surface area is 11,990 times that of the Earth'southward.
  • The Sun contains 99.86% of the mass in the Solar Arrangement.
    The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost 3 quarters Hydrogen, whilst most of the remaining mass is Helium.
  • The Sun is an virtually perfect sphere.
    There is a 10-kilometre departure between the Sun's polar and equatorial diameter. This means it is the closest thing to a perfect sphere that has been observed in nature.
  • The Sun will swallow the Earth.
    When the Sun has burned all its Hydrogen, it will go along to burn helium for 130 million more than years. During this fourth dimension, information technology volition expand to the point that information technology will engulf Mercury, Venus, and the Earth. At this stage it volition have go a red giant
  • The Lord's day will i day be about the size of World.
    Subsequently its red behemothic phase, the Sun will collapse. Information technology volition keep its enormous mass with the gauge volume of our planet. When this happens, information technology will take become a white dwarf.
  • The temperature within the Sun can reach 15 million degrees Celsius.
    Energy is generated at the Sun'south core, by nuclear fusion, every bit Hydrogen converts to Helium. Hot objects expand, the Sun would explode if information technology were not for its enormous gravitational forcefulness. The temperature on the surface of the Sun is closer to v,600 degrees Celsius.
  • Light from the Sun takes eight minutes to achieve Globe.
    The Sun is an boilerplate distance of 150 one thousand thousand kilometres from the Earth. Light travels at 300,000 kilometres per 2nd. Dividing one by the other gives us an gauge fourth dimension of 500 seconds (or eight minutes and xx seconds). Although this energy reaches Earth in a few minutes, it will already have taken millions of years to travel from the Sun's cadre to its surface.
  • The Sun travels at 220 kilometres per second.
    The Dominicus is 24,000-26,000 light years from the galactic center. It takes the Sunday 225-250 one thousand thousand years to complete an orbit of the centre of the Galaxy.
  • The distance from the Sun to Earth changes throughout the year.
    This is because the World travels on an elliptical orbit around the Sunday. The distance betwixt the ii bodies varies from 147 to 152 meg kilometres.
  • The Sun is center-anile.
    At effectually 4.6 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to go along to fire Hydrogen for approximately 5 billion years. The Sun is currently a blazon of star known as a Yellowish Dwarf.
  • The Lord's day has a very strong magnetic field.
    Magnetic energy released past the Sun during magnetic storms causes solar flares. Nosotros run into these as sunspots. In sunspots, the magnetic lines twist and they spin, much like a tornado would on Earth.
  • The Lord's day generates solar wind.
    The wind is a stream of charged particles. This travels at approximately 450 kilometres per 2nd through the solar system. Solar wind occurs when the magnetic field of the Sun extends into space.
  • Sol is the Latin for Sunday
    This is where the word "solar" comes from, which is used to draw things that are derived from, related to, or caused by the Sun

Sun Features

Sunspots

Sunspots are areas of the Lord's day's surface that appear darker than the surrounding areas, this is because they are cooler. They course in areas of stiff magnetic activity that inhibit rut transfer.

Solar Flares

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