this clock can be better whith more space .
from a clock animated included the solar system .
the scale cannot be ajdust 100 ‰ because the dim from clock
to have the right scale ( planete dim and space )
the clock must be bigger has that ( width=180 height=345)
the clock is transparent mode
and the planete are rotate too .
i am not expert of galaxie but the way rotation and speed
from planete here
must not come out the clock in this exemple .
the code to copy paste in custom mode is bellow
END OF CODE HERE ....
The galaxie
Have you ever wondered how big the solar system is ? The fact is that it's more than 7 billion miles wide. The number may not impress you much, but if you go out and do this activity, you'll realise how BIG it really is. Teachers, this is a perfect activity to do with your students...
Here's what you'll need :
- tape measure
- basketball
- marbles
- dried peas
- straight pins
- flour
First, we don't think that you'll be able to find the exact size for the marbles so just use the ones you can find. Use the tape measure to find out how many feet you normaly walk with one pace. Then you'll be able to count out the distance between the sun and the planets...
Now to start the activity, place the basketball down at one end of a playground or field. Count 36 feet from the sun and stick a pin in the ground. You've just place the planet Mercury. Keep pacing and mesuring and putting down the marbles, peas and pins for the other planets. We strongly recommend you to cut your distance in half because you'll surely run out of room before you finish the exercise...
- Mercury 36 feet pinhead (1/28 inch)
- Venus 62 feet dried pea (1/11 inch)
- Earth 98 feet (about 1/3 of a football field) dried pea (1/10 inch)
- Mars 142 feet pinhead (1/20 inch)
- Asteroid belt 258 feet (sprigle some white floor on the ground)
- Jupiter 486 feet shooter marble (1 1/4 inch)
- Saturn 891 feet shooter marble (7/8 inch)
- Uranus 1,794 feet marble (2/5 inch)
- Neptune 2,810 feet marble (2/5 inch)
- Pluto 3695 feet (nearly 3/4 mile) pinhead (1/58 inch)
