MENUMENU
The Sun is a star at the center of our solar system. Our Sun is a medium-sized yellow star that is 93,026,700 miles (149,680,000 km) from Earth. Its diameter is 865,121 miles (1,391,980 km). At its core, nuclear reactions produce enormous amounts of energy, through the process of converting hydrogen atoms into helium atoms (nuclear fusion). The Sun's absolute magnitude is +4.83. The solar mass is 1.99 x 1030 kg.Animation, images, and wonderful facts at

INTERESTING FACTS ABOUT THE SUN
•The SUN is about 109 times bigger than the Earth.
• about 1,300,000 Earths could fit inside the Sun .
•The Sun's mass is is about 333,000 times the mass
of the Earth.
•The Sun contains 99.8% of all of the mass of the SOLAR
System.
•the sun is like a fusion reactor. ITS core converts
hydrogen into helium. This releases huge amounts of
energy, which light and heat our planet.
• The sun is about five billion years oldfive billion years old and will live for
about another five billion years. MORE

How the sun affects the earthHow the sun affects the earth
It gives the earth energy: light and heat and sound and the whole electromagnetic spectrum.
The light gives us plants, the producers in our food chain, and gives us vision and color. The heat gives us weather and climate zones and many different biomes. Go to the next screen to see all of the kinds of energy included in the electromagnetic spectrum

The EARTH rotates (counter-clockwise ) around its own center or AXIS, once every 24 hours.
ONE rotation =24 hours = ONE day
The rotation of the EARTH causes NIGHT and DAY.
As the EARTH rotates, half of it faces the light of the SUN (DAY TIME,) while the other half is in the dark, facing away from the sun (NIGHT TIME.)
One entire rotation
takes 24 hours.24 hours.

Revolution does not mean to spin around your own center. it means to go around something else (as in an orbit.)

The average speed of Earth in its orbit is about 66,000 mphMotionsoftheearth.ppt, slide 4
REVOLUTION does NOT cause SEASONS. The axis of the earth is NOT straight up and down, but TILTS 23.5 °. This is what causes the SEASONS.

In 1647, a Polish astronomer, Johannes Hevelius, a Polish
astronomer, published the first study of lunar topography in a book
called Selenographia, “Description of the Moon.” It included
many excellent lunar maps with Latin names given to the
geographical features on the surface of the moon. Many of the
names given by him to the lunar mountains, craters, and other
features are still used. Click below for two different maps, one
more like his and one interactive.

Lunar eclipse .............. moon enter's Earth's shadow
Photo courtesy of Dennis diCicco.), Chapter 1, fig. 15; Thomas T. Arny, Explorations: an Introduction to Astronomy , McGraw-Hill
A lunar eclipse occurs when the Earth passes between the Sun and Moon, causing the Earth's shadow to fall on the Moon. Some sunlight leaks through the Earth's atmosphere casting a deep reddish light on the Moon. The photo inset shows what the eclipse looks like from Earth.

ONE ROTATION of the earth on it’s axis = ONE DAYONE MOON CYCLE =about 29.5 DAYS, which should be ONE MONTH. 12 X 29.5 = 354 days, 11 days short of the real SOLAR CALENDAR, so Julius Caesar, with the help of Greek science, changed our months to 30 or 31 day months which no longer match the moon cycles. February was given only 28 days, or in leap years, 29.OUR YEAR is a SOLAR year. It takes the SUN 365.25 days to complete ONE REVOLUTION around the sun,. so each year = 365 days, with the additional time added up into ONE EXTRA day in February, every fourth year.
