The Earth radiates back into space as much heat as it
receives from the sun.
Astronomers once believed a planet named Vulcan existed
between Mercury and the Sun.
If you were standing on Mercury, the Sun would appear 2.5
times larger than it appears from Earth.
By weight, the sun is 70% hydrogen, 28% helium, 1.5% carbon,
nitrogen, and oxygen, and 0.5% all other elements.
In 1890, there was no sunshine for the whole month of
December in Westminster in London.
Panama, because of a bend in the isthmus, is the only place

It takes approximately 12 years for Jupiter to orbit the
Honeybees navigate using the sun as a compass, even when it
is hidden behind clouds.

The Sun contains 99.8 percent of the total mass of the solar
The Sun is approximately 149 million kilometers from the
The Sun is flattened on the top and the bottom.
A galaxy of typical size about 100 billion suns produces
less energy than a single quasar.
A white dwarf has a mass equal to that of the Sun, but a

All the coal, oil, gas, and wood on Earth would only keep
the Sun burning for a few days.
The first populated land where the Sun will rise on a new

In the city of Reykjavik, Iceland, one can see the stars

over 1,000 times the mass of the Sun.
The Sun shrinks five feet every hour.
There may be a giant black hole at the center of our galaxy,
weighing as much as 4 million Suns. The black hole may be
capturing stars, gas, and dust equivalent to the weight of
three Earths every year.
The planet Venus does not tilt as it goes around the Sun, so
consequently, it has no seasons.
