They found the diameter of the Earth by measuring the angle of the Sun above the horizon at noon at two different places, Alexandria and Aswan. The 7 degree difference gave the Earth's circumference as 360/7 times the distance between those two cities.

Well, we cannot say that they are two new planets but they are new discoveries and considered as dwarf planets. Xena and Ceres
Yes, scientists have discovered many new planets outside the solar system, known as exoplanets. Statistical models indicate there are hundreds of billions of such planets within the Milky Way.
Earth's scientist have not found life on other planets to date.

Discoveries has been made especially in areas where man could not reach before. There un reached areas included outer planets, and very deep water oceans. The discoveries in these areas are made by unmanned robots, that go into these areas to make the discoveries.

An astronomer.
There are many important things that happened in the first 50,000 years of the universe. Many discoveries were made including dinosaurs, man, planets, and much more.
One of the discoveries that led to the modern view of the Solar System was that the orbits of the planets were ellipses. This was one of the key contributions from Johannes Kepler's laws of planetary motion, which replaced the earlier belief that planetary orbits were perfect circles.
