August 15, 2013/8 Comments//by. Life tenure for out-of control federal judges, including members of the Supreme Court will never be abolished unless there is an overwhelming public demand. I was asked for my view regarding a proposal to provide term limits for federal judges, including members of the U.S. Supreme Court. This is my response:
Asteroids are small, airless rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. In total, the mass of all the asteroids is less than that of Earth's moon. But despite their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future.
An asteroidâs composition is mainly determined by how close it is to the Sun. The asteroids that are nearest the Sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock.Silicates are very common on Earth and in the Solar System.enerally, there are three main types of asteroids: 1  Dark C (carbonaceous) asteroids, which make up most asteroids and are in the outer belt. 2  Theyâre believed to be close to the Sunâs composition, with little hydrogen or helium or other âvolatileâ elements.
