... 1. What is the most unusual characteristic of Earth? It has liquid water. No other planet has liquid water. 2. What is the most unusual characteristic of Uranus? It is tilted on its side. We see this because the rings are vertical, instead of horizontal, like on other planets. 3. What is the most un ...

Dark matter Dark matter does not give off observable energy in any EM wavelength, but can be detected by watching the behavior of space objects.

... 2. The mass of a black hole can be measured using Kepler’s third law. The electric charge of a black hole can also be measured, but is not considered in discussing black holes since they quickly become neutral through accretion. 3. Black holes are thought to spin very rapidly. A spinning black hole ...

Celestial Motion - Boris Boguslavsky
... Isaac Newton’s first law of motion states that an object in motion will stay in motion unless acted upon by an outside force. This also applies to objects at rest. Objects in space move because a force acted on them, or is acting on them. This is one of the core principles of physics and is vital to ...
