 * ** You can fit over 8 billion of or suns in the biggest star in the galaxy. **
 * ** our star make up pictures, one of them is a scorpian the way you find it is by seeing the red star and the two other stars that makes a triangle. **
 * ** you can't land a space ship on jupiter because it is a ball of gas. **
 * ** it takes 28 days for our moon to circle the earth. **
 * ** the moon can be seen as many differrent shapes. **
 * ** the sun is very small for a star, it is called a yellow dwarf. **
 * ** Mercuy is not the hottest planet even though it is the closest to the sun. **

WHAT IS THE DFFERENCE BEETWEEN THE INNER PLANETS AND THE OUTER PLANETS
inner planets :Outer planets They are smallerThey are huge Have solid surfaces and thin/no atmospheres.Balls of gas with no surface. They have greater density. They have smaller density.

Varied atmosphere. Similar atmossphere. Known by the acients. Not known by the ancients. Spins slowly. Spins quickly. Orbits the sun quickly. Orbits the sun slowly Few moons. Lots of moons.

No rings.They have rings. multiple space craft visitors.All outer planets visited by one space craft.

WHY DOES EARTH HAVE SEASONS   watch this video first http://www.youtube.com/watch?v=YyKvXX8iGE4   The Earth is tilted slightly and stays titled the same way as it orbits the sun. During Summer in the Northern Hemisphere, the North Pole is pointing towards the sun, granting it more sunlight and so hotter weather to the Northern Hemisphere.

During Winter in the Northern Hemisphere, the North Pole is pointing away from the sun and the Northern Hemisphere has less sunlight and colder temperatures.

WHY DOES THE MOON HAVE PHASES media type="youtube" key="AQRNzepe4wI?fs=1" height="385" width="480" Phases of the moon  .The phases of the moon are. 1. New Moon.Day 0 2. Waxing Crescent. Day 4 3. First Quarter. Day 7 4. Waxing Gibbous. Day 10 5. Full Moon. Day 14 6.Waning Gibbbous. Day 18 7.Last Quarter. Day 22 8. Waning Crescent. Day 26 As the moon circles the Earth, the shape of the moon appears to change; this is because different amounts of the illuminated part of the moon are facing us. The shape varies from a full moon (when the Earth is between the sun and the moon) to a new moon (when the moon is between the sun and the Earth). DISCRIBE THE FORCE CALLED GRAVITY  I think the force of gravity is when you at least weigh something you touch the ground. Our atmosphere helps us not to float away. This is the the internet resault: The natural force of attraction between any two massive bodies, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
