I don't know what "elliptical planet" is supposed to mean, but by any reasonable definition I can think of, no, all planets are "elliptical planets".
Who was the first astronomer to consider ellipses as orbits?
i think you mean elliptical, and i believe it was Johannes keplar
Why do people think mars is earths twin?
Mars is similar in size to Earth, and they were both created during the formation of the Solar System. Their orbits are also close to each other.
Did Newton discover that gravitation caused planets to follow irregular orbits?
No, Isaac Newton discovered that gravitation causes planets to follow elliptical orbits. This was a major breakthrough in understanding celestial motion and laid the foundation for his law of universal gravitation.
How are planets kept in there orbits?
The gravitational pull of the sun keeps the planets in orbits... Although some people think it is magnetism....
Why do people think that Pluto is a planet?
Because it orbits the same star as we do (the Sun).
Which change in the earths land is sometimes increased by people?
i think it is weathering
How was the discovery of the planets orbits shape made?
Johannes Kepler made the discovery of the planets' elliptical orbits in the early 17th century. He used observational data gathered by Tycho Brahe to formulate his three laws of planetary motion, which defined the precise shape and behavior of the orbits. This groundbreaking work laid the foundation for our modern understanding of planetary motion.

Why do you think other religious men condemned the ideas of Copernicus if he was providing that god created a more perfect system?
Copernicus produced an alternative model of the planets that had the Sun at the centre, which contradicted the religious view at the time. The church was unwilling to change its theology without adequte proof. The wisdom of the church's attitude was eventually proved when Copernicus's model was rejected in favour of one discovered by Kepler with elliptical orbits. It also had the Sun at the centre, and when the elliptical orbits were confirmed by Newton's theoretical discoveries the model was generally adopted.
How are planets asteroids and comets orbits alike?
Rock and/or metallic solids - virtually 100% for a typical asteroid, and a goodly amount (some astronomers think more than half) in a cometary nucleus. They also share in common the fact that they orbit around the sun.
What is a good price to pay for an elliptical machine?
According to Lance Armstrong, you get what you pay for when purchasing elliptical machines. I think a visit to his website would provide the information you need about purchasing elliptical machines: www.livestrong.com/.../380796-what-are-the-best-elliptical-machine
