The highest uncompressed density can be found on Earth, specifically at its core. The core is composed mainly of iron and nickel, which gives it a higher density than other planets in our solar system.

Eccentricity can be found in mathematics problems. Eccentricity is another term for the symbols and shapes we use when we are writing out most advanced mathematics problems.
The solar system is found between the orbits of two planets, with the innermost known planet being Mercury and the outermost known planet being Neptune. The solar system also consists of other celestial bodies such as dwarf planets, moons, asteroids, and comets.
There are 464 extrasolar planets, and 8 planets within our Solar System. This makes a total of 470 known planets.
The majority of the angular momentum of the solar system is found within the orbital motion of the planets around the Sun. This motion results in the spinning of the planets on their axes and the overall rotation of the solar system as a whole.
Planets
There is 8 planets in our solar system now, becuase scientists no longer classify Pluto as a planet. There where about 400 planets found so making it about 399 so about 391 exo-planets have been found. Hope that answers your question!
Our model of how the Solar System operates was discovered by Kepler with his three laws of planetary motion, published in 1609. He took an entirely new approach to planets' orbits after new and accurate observations of the planets' positions had been carried out by Tycho Brahe with the latest equipment. After a lot of detailed geometric work on the orbit of Mars Kepler found that an elliptical orbit fitted the way Mars moves, more closely than anything else. From that he deduced the famous three laws. However it was not until the time of Isaac newton that they started to understand why the planets move as they do, after the force of gravity was discovered. Newton's major discovery was that when the planets move under the inverse-square law of gravity, they must follow Kepler's three laws. The circles and epicycles of Copernicus's system represent the planets' orbits with good accuracy provided the eccentricity factor is small. This theory was replaced by that of Kepler. Kepler's decision to study Mars, which has an orbit with 9% eccentricity (higher than the other major planets) was a good choice because it shows up the difference. Even with this eccentricity the the minor axis of the orbit is less than 0.5% shorter than the major axis.
