I hope the 6 markers are on international collaboration or the advantages of remote telescopes :tongue:

if they're on anything else I'm gonna be so stuck!
I've done tonnes of revision but I don't feel prepared at all...hopefully it will be like C7!!

Retrograde motion is the apparent motion where plants seem to be going 'backwards'
The motion is recorded from Earth, you see the movement of planets in respect to Earth's orbit and fixed stars
Different planets travel at different speeds on different planes, inner plants are faster than outer plants around the Sun
An example of retrograde motion is when a planet 'overtakes' Earth due to its speed, but then the Earth overtakes that planet - forming a loop pattern

I dont think the Great Debate are going to come up, since it did last year and that's possibly the best thing for a 6 marker :frown:

Hopefully nuclear fusion comes up since it didn't last year :biggrin:

I'm actually quite scared for this exam since it can go either way; it's either going to be really good and straightforward or it's going to end up being really weirdly worded D: And knowing OCR this year, i don't know what to think :tongue:

yeah but what type of 6 mark question would they give? or will they most likely give you a scenario?

"Ranjit is an astronomer and is looking on the internet. He looks at the motion of the outer planets and comes across a picture of the outer planet's movement in a year.

Ranjit says that they're going backwards. Explain why Ranjit is wrong using the images and your own knowledge of Physics."

Hey don't be worried!
International collaboration is just where scientists from all over the world get together to launch things like satellite telescopes or build big Earth telescopes. It's good because they can share expertise and knowledge and also the cost of the project is shared between everyone :smile:

The advantages of remote telescope are just that they can be controlled by computer so people don't have to pay for the scientists to travel to the telescope. Also if the telescope is in space, it can be controlled by a computer to precisely track a star whilst the Earth rotates on it's axis :') good luck!!

ocr 21st century P7 final exam!!
