An astronomical unit (AU) is defined as the average distance between
the solar system and Alpha Centauri
the Earth and the Moon
the Milky Way Galaxy and the Andromeda Galaxy
the Earth and the Sun
The Sun and the planets of the solar system are located in a spiral galaxy , called the Milky Way .
Which numbered area on the model best represents the location of the Sun in this galaxy ?
It is important to have an idea about the distances between and relative sizes of celestial objects in the
solar system. In Part 1 we will pretend to shrink the solar system until its center piece, the Sun, is 67.3 cm
in diameter. This will represent the Sun which is 1,390,000 km in diameter. The scale of our model is thus:
67.3 cm
= 4.84 x 10-5 cm
km
Scale
1, 390, 000 km
To find the size or distance between objects in centimeters for the model, simply multiply the actual size
or distance in kilometers by the scale factor above.

- The distance from the Sun to the nearest star is about 4 1016 m. The Milky Way galaxy (Fig. P1.31) is roughly a disk of diameter 1021 in and thickness 1019 m. Find the order of magnitude of the number of stars in the Milky Way. Assume the distance between the Sun and our nearest neighbor is typical. Figure P1.31 The Milky Way galaxy.arrow_forwardRaising a number in scientific notation to a power is easy: (5 x 105)² = (5)² x (105)² = 5 x 5 x 105 x 105 = 25 x 10(5 × 2) = 25 x 1010 = 2.5 x 101¹1 Keeping this in mind, what is the volume of the sun in km³? The radius of the sun is about 7 x 105 km, and the volume of a sphere is 4/3 x Pi x R³. (Use 3.14 for Pi, and enter your answer with two decimal places). km³ 3 What is the average density of the Sun?

So a planet that is twice as far from the Sun as Earth receives (1/2)2=0.25 times (25%) as much light and a planet that is three times as far from the Sun receives (1/3)2=0.11 times (11%) as much light.
