When was Mark Plantery born?

Effects on mining copper on the environment?
This is hazardous, it is extremely dangerous on the environment. You find, that most effects lead to swamps, dirty river banks, washed up sloth, and damaged plantery. It ruins habitats, all for a selfish cause- money. Money doesn't grow on trees, and leaves won't if they carry on mining. Get a normal job, for normal people. Many thanks, environmentally friendly angry person.
Suns gravity keeps what in an oval shaped orbit?
The sun does not "keep" the planets in an ellipse orbit but only that it is so because the odds of a celestial body having a perfectly circular orbit are very small. But yes all the planets do have ellipticall orbits of varying eccintricities. There are laws that govern planetary orbits devised by Johannes Kepler. For more info look up Johannes Kelper's Laws of Plantery Orbits.
Why is Pluto considered to have the weakest surface gravity?
Back when Pluto was still listed as a planet it was considered to have the weakest gravity of all the solar system's planets. Now that Pluto has been demoted from planetary status, the planet with the weakest surface gravity is Mercury. While Pluto's gravity is weaker than that of any planet in the solar system, there are still many non-plantery objects with weaker surface gravity.
