Basic Properties of the Stars

Basic Properties of the Stars. The Sun-centered model of the solar system laid out by Copernicus in De Revolutionibus (1543) made a very specific prediction: that the nearby stars should exhibit parallax shifts with respect to the distant background of

SCALES: PLANETARY

SCALES: PLANETARY. Problem for Astronomers: there is no sense of depth from looking at the sky. Comet Hale-Bopp: 10 light- minutes away. Andromeda Galaxy: 2 million light-years away. Proximity on the sky does not tell us about proximity in space.

MEASURING DISTANCE TO THE STARS

How do astronomers measure the distance to the stars? Measuring Tape? Radar? Obviously, you cannot use a tape measure Bouncing radar off the surfaces of stars would not work because: (1) stars are glowing balls of hot gas and have no solid surface to reflect the radar beam back
