Copernicus' heliocentric system gave the Earth-Sun distance special importance; it could be used as a measuring ruler within the Solar System (Table 5.1). Kepler's Third Law emphasized the same thing: the times of revolution around the Sun, obtained from observations, determine the relative ...
Sure, the Solar System is big, but it's probably a lot bigger than you think, thanks totextbook representationsthat squeeze all the planets and their orbits into one page. Even at the speed of light, it takes more than 40 minutes to get from the Sun to Jupiter (a journey you canexper...
(rocky) planets:Mercury,Venus,Earth, andMars. Standing at the Earth, look at the image of the Sun. That should have similar angular size (‘subtend a similar angle’) to the real sun in the sky. And don’t forget that the real sun seems bigger than it is because it is so bright....

The Laboratory for Astrophysics (LfA) at the National Air and Space Museum (NASM) is proposing a new exhibit: an outdoor model of the Solar System on the National Mall, dedicated to the Spirit of Human Exploration. At one ten- billionth of the size of the actual Solar System, the model...
A scale diagram of the orbits of the eight planets in our solar system. If we have done our calculations correct, the scale is approximately 16,345,000,000,000:1 (so one centimetre on an adult t-shirt will be roughly equivalent to slightly more than 163 million km). The sun, by comp...
The most remarkable discovery of recent years in the study of the interstellar medium has been the identification of spatial structures of sizes down to those of a few times the mean Earth-Sun distance (an Astronomical Unit , AU). Solar-System Scale microstructures are detected in cool clouds ...

This information is used to derive constraints on the timing of processes and events, which took place in the early solar system. Using reasonable assumptions, a timeline is constructed where the estimated age of the solar system is ~4571 Ma. This age is taken to mark the time when most ...
