Extra Solar Planets Interactive (135.0K)
Nu Andromedae has three jovian type planets orbiting around it. Let's use the orbit of the innermost, and Newton's revision of Kepler's third law, to weigh its star.
While in the previous question, we used the inner most jovian of Nu Andromedae to weigh the star, now let's look at the distances of the two outer jovians that orbit this star, with comparisons to our solar system.
On June 8, 2004, the planet Venus transited the Sun. We now know of several cases where hot jupiters also pass in front of their stars, and even amateurs with photometers are helping monitor hundreds of stars for such recurrent dimmings. What can they tell us about the planets involved?
In 1995, the first planet orbitting another star was discovered, and since then, the count of other solar systems has passed one hundred and growing daily. But to date all are comparable to at least Uranus in size. How can we find Earths instead?
