Solar System - Wikipedia
WebThe principal component of the Solar System is the Sun, a low-mass star that contains 99.86% of the system's known mass and dominates it gravitationally. The Sun's four largest orbiting bodies, the giant planets, account for 99% of the remaining mass, with Jupiter and Saturn together comprising more than 90%.
How Bright Are the Planets? - Sky & Telescope
WebMay 26, 2020 · Planetary magnitudes as seen from Earth vary with their angular distance, or elongation, from the Sun. An elongation of 180° corresponds to solar opposition and 0° corresponds to solar conjunction. This plot shows daily magnitudes over a period of about 50 years. Anthony Mallama & James Hilton.
