The
Sun: The Basics
The sun is a star, a hot ball of glowing
gases at the heart of our solar system.
Its influence extends far beyond the
orbits of distant Neptune and Pluto.
Without the sun's intense energy and
heat, there would be no life on Earth.
And though it is special to us, there
are billions of stars like our sun scattered
across the Milky Way galaxy.

Sun
mass
The Sun is the center of our
solar system and makes up 99.8 percent
of the mass of the entire solar system.
Interesting
facts
If the Sun were as tall as a typical
front door, Earth would be about the
size of a nickel.
At the equator, the Sun spins once about
every 25 days, but at its poles the
Sun rotates once on its axis every 35
Earth days.
As
a star, the Sun is a ball of gas (92.1
percent hydrogen and 7.8 percent helium)
held together by its own gravity.
The Sun does not have any rings.
Without
the Sun's intense energy, there would
be no life on Earth.
But
orbited by eight planets, at least five
dwarf planets, tens of thousands of
asteroids, and up to three trillion
comets and icy bodies.
The
Sun’s visible surface sometimes has
dark sunspots, which are areas of intense
magnetic activity that can lead to solar
explosions.

The
sun has an age of 4.5 billion years
and is 100 million times as large as
Earth. Yet it is quite a mediocre star
on the universe scale. For humans, the
sun is invaluable.
The sun consists of hot hydrogen and
helium. At the heart of the sun huge
amounts of energy are released. Even
the smallest differences in the Earth's
distance to the Sun mean significant
temperature differences. Without the
Sun the Earth would be lifeless.

New
Zealand is country where sun rise is

Day.
The
