My Space page! SUN Mercury  Venus  Earth  Mars  Jupiter  Saturn  Uranus  Neptune  Pluto NASA has anounsed that a small asteriod will zip by Earth on Tuesday the 12th of October. NASA has said that there is no chance of the asteriod hitting Earth, or even entering the atmosphere for that matter. The asteriod, (2010 TD54) will make its closest pass at 6:51 am. It will be 45,000km away from Earth. It will be passing over Southeast Asia, near Singapore at the time. I, personaly, would be very exited to see a asteriod pass over my head.

THE PHASES OF THE MOON

The phases of the moon are the stages that the moon goes through to get back to a stage called 'the new moon'. The phases are as follows; new, waxing creasent, first quater, full moon, waxing gibbous, new, wanning gibbious, last quater & wanning creasent. It takes 8 days for the Moon to circle the Earth once, but it takes 9 & a half days for the Moon to go from new Moon to new Moon. That is because it is only a new Moon when the Sun is alinged with the Moon. The Earth is moving, so for the Moon to be compleatly alinged with the Sun, it has to go that bit further (another 1 & 1/2 days).

GRAVITY

Gravity is the force pulling together all matter, meaning anything you can touch. The more matter, the more gravity. So anything with a lot ﻿of matter such as stars, moons and planets has a stronger gravitational pull.

Mass is how we measure the amount of matter in something. The bigger something is, the more gravity it has. When we walk on Earth, the Earth pulls on us and we pull back. Since the Earth is bigger than us, our gravitational pull is not strong enough to move the Earth from its orbit around the Sun. But the pull from the Earth is stong enough to make us fall flat on our faces.

Gravity also depends on how far you are from something. Thats why we are still standing on Earth, instead of being pulled of into the Sun, which has many more times the gravitational pull that Earth. Thats also why we are stuck in an orbit around the Sun.

THE EARTH'S SEASONS

The earth's seasons are NOT caused by the varying distance away from the Sun. The actual reason is because of the Earth's tilt. As the Earth orbits the Sun, the tilt of the Earth causes most of the heat from the Sun to be directed at a certian parts of the Earth at different times. The other areas are colder because they aren't getting as much light as the rest of the Earth.The southern hemesphere seasons are as follow; summer: 1st December - 31st February, Autumn: 1st March- 31st May, Winter: 1st June - 31st August, Spring: 1st September - 30th November.

THE INNER AND OUTER PLANETS

The differnce between the inner and outer planets is that the inner planets are rocky and the outer planets are gas. The other difference is that the inner planets don't have the denser atmosphere that the outer planets have. Mercury, Venus, Earth and Mars all have higher temperatures than the exteriors of the outer planets, Jupiter, Saturn, Uranus and Neptune. The outer planet are mainly gas gaints, with very hot lower atmospheres, caused by imense pressure. Jupiter and Saturn's atmospheres are mainly hydrogen, but Uranus and Neptune's insn't. That is because their atmospheres contian higher levels of water, methane and ammonia. All of the gas gaints have rings, but the most visibial rings belong to Saturn. Bibliography
