1. Mercury
... Mercury is the closest planet to the Sun and the eighth largest. ... An account of the non-discovery of a planet inside Mercury's orbit. ... Heraclitus even believed that Mercury and Venus orbit the Sun, not the Earth. ... Until 1962 it was thought that Mercury's "day" was the same length as its "year" so as to keep that same face to the Sun much as the Moon does to the Earth. ... Actually Earth's density is due in part to gravitational compression; if not for this, Mercury would be denser than...

14. (S-7a) The Black Hole at the Center of our Galaxy
... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
