Distance between Stars
The distance between the Sun and our Earth is 150’000’000 km / 93’750’000 mi or 1 AU (Astronomical unit)
Pluto has a very excentric orbit that brings him sometimes inside the orbit of Neptune
The distance between our Sun and the nearest star is about 4.3 light years or etwa 40 Billion km. This distance is so enormeous, that in a model where our
Earth is 25 mm (1 inch) distant from the sun, the distance to the next star would be 6.5 km/4 mi!
Our home galaxy, the Milky Way, inhabits round about 100’000’000’000 stars. With its spiral arms, it has a diameter of about 100’000 light years.
