Interesting Facts
|
| The Sun is by far the
largest object in the solar system. It contains
more than 99.8% of the total mass of the Solar
System |
| The solar wind is
responsible for the ion tails of comets and has
measurable effects on the trajectories of
spacecraft. |
| The Sun is a yellow main
sequence star about 840,000 miles in diameter,
which is more than 100 times the diameter of the
Earth |
| In the Sun's core, hydrogen
is converted to helium by nuclear fusion,
releasing energy in the process. |
| The Sun's mass is 300,000
times that of the Earth |
| Sunspots have a temperature
of 4,800 C, they appear dark by contrast with the
brighter surrounding surface, the temperature of
which is 6,000 C. The life of a sunspot can be as
short as a few hours as long as several months. |
| Never look directly at the
Sun: it is extremely dangerous to use binoculars
or a telescope to look at the Sun as this can
cause permanent blindness |
