The ABC’s of the Solar System

By: Homeroom 101 & 102

• A is for Air Glow

• The natural glow of the night sky due to reactions that take place in the Earth's upper atmosphere.

• Most of visible airglow comes from oxygen atoms and molecules.

• There are a lot of other factors involved with airglow as well, such as temperature and altitude.By: Brian

B is for Black Hole

A region of space around a very small object within which the gravitational field is so strong not even light can escape.

Black holes are created when a red super giant star collapses, causing a supernova explosion. A black hole does not have a surface like a planet or a star.

By: Gianna

C IS FOR CRUST• The thin rocky surface of a planet or moon. • The crust holds in Earth's mantle.• Under the Earth is the oceanic crust.

By: Owen

D IS FOR DOUBLE STAR• Two stars that are drawn to each other by their

respective gravitational pulls.

By: Sharon

E is for Extraterrestrial• It means not of or beyond the Earth. It refers to anything that doesn't b long to planet Earth. An extraterrestrial would be a being from another planet or

an alien.

By: Parker

F is for Flare

A sudden burst of energy from a star like the sun.

By: Shanyah

G IS FOR GALAXY• A large group of stars, bound together by gravity. Quite often,

the galaxy will form a spiral or circular shape. • The Milky Way has a special shape.• A galaxy is a massive group of stars, star clusters, interstellar

gas and dust, and dark matter which is all gravitationally bound together.

J is for Juliet Juliet is a moon of Uranus

By: JUDAH

K IS FOR KUIPER BELT

. A region of solar system beyond the orbit of Neptune believed to contain many comets and asteroids.

By: Tristen

L is for Larissa• Larissa is a moon of Neptune.• Larissa is only about 30,300 meters from

Neptune’s clouds.• It circles the planet in 13 hours and 18 minutes.

By: Dylan

M is for Mars

Mars is the fourth planet from the sun and the last of four inner planets.

In mythology, Mars is the Roman God of War. Mars has two moons, Phobos and Deimos.

By: Louis

M is for Mercury• Mercury is the closet planet from the sun and smallest traditional planet in the solar system .

• Mercury is so small and so close to the sun it’s impossible to see .

• Mercury’s surface looks very similar to the moon’s.

By: Jahnea

M is for Mercury• Mercury is named after the Roman messenger to the gods, it is the closest to planet to the sun.

• Mercury has no atmosphere at all. Sunlight reflects off of it’s surface.

• Mercury can only be seen just after the sun has risen and just before the sun sets .

By:Taliyah

M is for Mundilfari • Mundilfari is a moon of Saturn.• Mundilfari was found in the year 2000.• Brett J. Gladman and a team of other people found Mundilfari.

By: Jada

N IS FOR NEPTUNE

• Neptune is a twin planet to Uranus and the eighth planet from the sun.

• It was discovered in 1846 by Johann Gotfier.

• Neptune’s closest moon was discovered in 1989 by Voyager.

By: Bailee

O IS FOR ORBIT• THE PATH ONE OBJECT TAKES AROUND ANOTHER• AN ORBIT IS A PATH THAT AN OBJECT TAKES IN SPACE.• AN ORBIT GOES AROUND A STAR OR A PLANET.

By: Faith

P IS FOR POLYDEUCES• Moon of Saturn• The semi-major axis of the orbit is 377,200 km, which

is the furthest point from the center to the edge of an elliptical point.

• The mass is 4,496,005,299,292 kg and the volume is 9km3.

By: Nymir

R is for Revolve

. When something is moving in a circle around anther object. • The moon circles the earth.

By Evan

s is for Saturn

– It is a gigantic planet with huge rings.

By: Jalyssia

S is for Sun• At the very center of the solar system is the sun.

By: JAMAL

T IS FOR TRITON• Triton is the largest moon of Pluto.• It was discovered in 1846. • 5 days and 21 hours to complete an orbit.

By: Troy

U is for Uranus

It’s the seventh plant. Uranus is named after the Greek god Uranus.

A space craft would have to travel 1,500,000,000 kilometers to reach Uranus.

Uranus’ pale blue color is caused by the methane in it's atmosphere which filters out red light.

W is for White Dwarf

Dense remains of an intermediate mass star like the sun that has collapsed.There are two different types of white dwarf stars.Over time though, the hydrogen at the core diminishes.
