Q4 Orbit is a word we hear quite often.An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like the Earth or the Moon. Q6 The differnce between the outer planets and the inner planets are....   Orbiting the Sun are eight planets. Despite all of these planets being different from each other, they can be put into two groups. One group are the four planets closest to the Sun - Mercury, Venus, Earth and Mars. These are known as the Inner Planets or the Terrestrial Planets. The other group are the four planets furthest from the Sun - Jupiter, Saturn, Uranus and Neptune. These are known as the Outer Planets or the Gas Giants. The two groups are separated by the Asteroid Belt, a region of thousands of asteroids in orbit of the Sun between Mars and Jupiter.

Inner Planets Outer Planets = Space Lab = This is 10 facts I learnt. 1. Saturn has 62 moons, not 60. 2. An asteroid hit Earth 65 billion years ago to make the dinasaurs get extinct. 3. At night when you are looking for the scorpion, look for a red star which is the scorpions heart. 4. Jupiter has 63 moons. 5. It takes 29 and a half days for the Moon to rotate the Earth. 6. The Lunar eclipse is at night 7. The Solar eclipse is at day. 8. Black holes are dead stars that have exploded 9. The Sun might explode one day 10. The white bits of the Sun are the hottest.
 * The inner planets and the outer plants are divided by theasteroid belt.
 * The inner planets are small and comprised or mainly rock and metals.
 * The outer planets are large and are comprised of mainly gases and ices.

**Why does Earth have seasons?** As you probably know, the earth rotates in space spinning. it orbits around the sun. Imagine there’s a line passing through the Earth, from the North pole to the South pole, and then out into space in both directions. This is called the axis of rotation. And in the case of the Earth, axis of rotation is tilted. Instead of going directly up and down, compared to the axis of rotation for the sun, this tilt makes all the difference to the climate here on Earth, and that gives us seasons. We don't really know. We can define what it is as a field of influence, because we know how it operates in the universe. And some scientists think that it is made up of particles called gravitons which travel at the speed of light. However, if we are to be honest, we do not know what gravity "is" in any fundamental way - we only know how it behaves.Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. Sir Isaac Newton discovered that a force is required to change the speed or direction of movement of an object. He also realized that the force called "gravity" must make an apple fall from a tree, or humans and animals live on the surface of our spinning planet without being flung off. Furthermore, he deduced that gravity forces exist between all objects.

The Moon is a sphere which travels once around the Earth every 29 days. As it does so, it is illuminated from varying angles by the Sun. At New Moon, the Moon is between the Earth and Sun, so that the side of the Moon facing towards us receives no direct sunlight, and is only lit by dim sunlight reflected from the Earth. As it moves around the Earth, the side we can see gradually becomes more illuminated by direct sunlight. "Have you ever wondered what causes the moon phases? We all know that its appearance changes over time. But why? The good way to understand the phases of the moon is to examine an earth-moon-sun diagram"

Solar eclipse: Solar eclipse is when the moon passes between the Sun and the Earth. From what I think it is when the Earth is orbiting the Sun facing each other. As you can see the Earth is orbiting the Sun and they are facing each other.

Lunar eclipse: A lunar eclipse occurs when the moon passes behind the earth such that the earth blocks the sun’s rays from striking the moon. This can occur only when the Sun,Earth and moon are aligned exactly, or very closely so, with the Earth in the middle.
