Solar System

Thanx the infomation was great.

I have have had a good look at your website, and all I can say is what a great job.

I also have a question. I heard that Mercury's days are really weird. Is a day on Mercury equivalent to an Earth day or is it different because of Mercurys size compared to earth?

It's quite hard to explain exactly how Mercury's orbit works, but I tried a couple of days ago, so just scroll down a little for an explanation.

I had to do a homework that I had to find 10 facts about the Solar System. When I found this site I got the information that I wanted and I learned a lot more about it. Thank you.

Great site! Really cool facts - love science, physics, space! Everything is totally amazing. My ambition is to meet Stephen W. Hawking and I want to be a cosmologist! This site is great for general info about our Galaxy. The scale model put everything in to perspective!

I also just wanted to ask you why the Sun sets twice on Mercury? I thought I understood - but now I am confused.

The Sun doesn't really set twice on Mercury, although it does have a rather strange relationship between a day and a year. This happens because the length of a day and the length of a year on Mercury are so similar. This page explains the effect in more detail.

Great site, good info, handy for projects and the like. Best bit: Scale model of the solar system. Really puts things in perspective. Well done.

Thanks for the celestial website Simon. I live in the vicinity of Kitt Peak and Mount Graham observatories, so I think its rather ironic that I find Solar System websites in the U.K.

I have recently read The Odyssey Series by Arther C. Clarke and found a compelling urge to see the Solar System for what it really is - without leaving Earth. Well done, I'm interested in seeing further still now!

I am interested in space and I think all of the space programs that you get on the computer are great fun.

I needed this information for school and it worked very well. Thank you.

I have been looking on your website and I find it quite amazing. It makes me wonder how they are so big and far away. I was wondering if you could send me more information about planets like, pictures and facts and any other things. I thank you if you can send it. I need information for a project at school. Is this site in America and do you work in a space centre or station and look through a huge telescope?

I'm afraid that all the information I have is already on my website. If you need more information and pictures, I have produced a links page, which lists many more excellent astronomy websites.

I work at the University of Nottingham in England in the Astronomy department. I do sometimes get to go out to the big telescopes, although only for a couple of days a year.
