Universe to scale


photo1
This shows the size of the Earth compared to the other inner planets in our solar system. The inner planets have terrestrial surfaces like Earth.



photo2
This shows the size of the Earth and inner planets compared to the larger outer planets in our solar system. The outer planets are beyond the main asteroid belt and are nicknamed the "gas giants" due to their size and composition.

This shows the size of the planets in our solar system compared to the Sun. Our Sun is different from most stars in the Milky Way galaxy. It is a single star rather than a binary star, among the most massive 10% of nearby stars, has about 50% more heavy elements than other stars of its age and type, and only 33% of their variation in brightness. All these factors are necessary to enable our lives on Earth. Approximately 99.9% of all the matter in the solar system is inside the Sun.

This shows the size of our Sun compared to other stars. Sirius is a brilliant white binary star that is the brightest star in the night sky and is about 8.6 light-years away from the Sun. Pollux is the brightest star in Gemini and is part of a double star system. It is about 33.7 light-years from the Sun. Arcturus is the brightest star of the northern hemisphere in the spring and the fourth brightest star in the Earth's night sky. It is located about 36.7 light-years from the Sun.

This shows the size of the Sun compared to some of the largest stars. Aldebaran is a binary star system located around 65.1 light-years from the Sun. Betelgeuse is a red supergiant estimated to be located around 430 +/- 100 light-years from the Sun. Anteres is a supergiant that is the 15th brightest star in the night sky. It is estimated to be about 600 light-years from the Sun.
