A sense of scale.

Let's make a scale model of some nearby celestial objects. For this, I'll be using the scale 1:1.25E10, or 1 inch to 200,000 miles.

At this scale, the Sun is about the size of a grapefruit (11 cm).
The Earth is about the size of a poppy seed (1 mm), and is about the length of a city bus (13 m) - from the Sun.
The Moon is about the size of a grain of sand (0.25 mm), and is a peanut's length (3 cm) from the Earth.

Jupiter is about the size of a blueberry (1 cm), and is half a city block (61 m) from the Sun.
Saturn is about the size of a cranberry (8 mm), and is a whole city block (113 m) from the Sun. Saturn's rings are the size of a quarter (2.2 cm), except that they're thinner than a strand of DNA (1.57 nm).

Proxima Centauri is the size of a small strawberry (1.5 cm), and is 3,135 km from the Sun - about the distance between New York City and Salt Lake City, or London and Cyprus, or Hong Kong and Jakarta.

The Milky Way Galaxy extends halfway from the Earth to the Sun (74 million km).
The Andromeda Galaxy is about the same size as the Milky Way, and sits somewhere between the orbits of Saturn and Uranus (1.9 billion km, or 12.6 AU).
