THE SUN, EARTH, AND MOON
By: Logan Kennedy, Kevin Roberts 9th
Our Solar System
Home galaxy: Milky Way spiral Home star: Sun G2V Home Planet: Earth Home Planet’s Moon(s): Moon Other planets in Solar System: Mercury,
Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
The Sun
It is the center of the solar system Gravity: 27.94 g Along with the moon creates tides on earth. Size 1,392,000 km about 109 times earth Time Sun up –Sun down Classified as a G2v star
Earth
Only known life supporting planet Tides caused by Sun and Moon. Neap are weak tides caused by when the
Sun and Moon pull from different directions.
Spring tides are powerful tides caused by when the Sun, Earth, and Moon are in a straight line
Seasons are caused by the sun and Earth’s tilt
Magnetic field creates aurora
Earth’s Tides
Neap Tides: Sun and Moon pulling from different directions
Spring Tides : Sun and Moon In same line
Earth’s Season
Due to the Earth’s tilting the Sun shines more on a certain place more than others. Causing the Sunrise-Sunset relation times to differ.
Solstice: Earth is largely tilted causing the Hemi-spheres’ Sunrise-Sunset relation times to be shorter or longer than the norm.
Equinox: Time in both hemispheres’ are almost equal.
Northern hemi. Solstice-Equinox Times.• Summer Solstice :North hemi. time is longest on this
day• Autumnal Equinox :About the same with Southern hemi. • Winter Solstice: North hemi. Time is shortest on this
day• Vernal Equinox: About same time as Southern hemi.

Aurora
Earth’s magnetic field (magnetosphere) blocks it from the Sun’s deadly radiation.
When the magnetosphere can not hold anymore it slingshots the particles back into a wondrous light show.
Auroras only appear at latitudes 3 dg. to 6 dg.
Known aurora colors: Green, Red, Indigo, Blue, and Ingdigo
The Moon
Only natural satellite (moon of earth) Orbit at 384,400 km from Earth Diameter 3476 km Mass 7.35e22 kg Due to the Earth position and rotation
and the moons position and rotation along with the sun it is shown to have various shapes though it is because of the sun shine on it and it and us rotating around the sun.
The eight main phases of the Moon

Gravity
Gravity is one of the four fundamental forces of physics; Electromagnetism, weak nuclear force, strong nuclear force, and of course gravity. The other forces are stronger than gravity because gravity must go through the 4 dimensions Height, Depth, Length, and Time or Space-time.
