English: Comparison of angular diameter of the Sun, Moon and planets with the International Space Station (as seen from the surface of the Earth), the 20/20 row of the Snellen eye chart at the proper viewing distance and typical human visual acuity. The dotted circles represent the minimum angular size (when the celestial bodies are farthest ...
The Sun, planets, dwarf planets and moons are at scale for their relative sizes, not for distances. A separate distance scale is at the bottom. Moons are listed near their planets by proximity of their orbits; only the largest moons are shown. Only the largest moons are shown.

The Sun at Toijalan Yhteiskoulu -school. Akaa Solar System Scale Model is located at the center of the city of Akaa, Finland. The Sun is located at the school campus of Toijalan Yhteiskoulu in Toijala district. The scale of the model is 1 : 3 000 000 000, meaning that each centimetre in the scale model represents 30
English: This 10 billion to 1 scale model of the Solar system can be placed into hallways of most school buildings. The inner solar system can be placed inside, while some or all of the the outer planets are typically placed outside, with Neptune at a distance of 450 meters from the Sun. Students can copy the drawings by hand on index cards or cut them out and glue or tape to the cards.
The scale of the planets is the same as the scale between them, and the planets are represented by everyday objects; the Earth is a peppercorn, Jupiter is a walnut, and Neptune is a coffee bean.

Planck length; typical scale of hypothetical loop quantum gravity or size of a hypothetical string and of branes; according to string theory, lengths smaller than this do not make any physical sense. [1] Quantum foam is thought to exist at this scale. 10 −24: 1 yoctometer 142 ym Effective cross section radius of 1 MeV neutrinos [2] 10 −21
Kepler's laws provide precise ratios of the orbit sizes of objects orbiting the Sun, but provide no measurement of the overall scale of the orbit system. Radar is used to measure the distance between the orbits of the Earth and of a second body. From that measurement and the ratio of the two orbit sizes, the size of Earth's orbit is calculated.
The plate scale of a telescope connects the angular separation of an object with the linear separation of its image at the focal plane. If focal length f {\displaystyle f} is measured in mm, the plate scale in radians per mm is given by angular separation θ and the linear separation of the image at the focal plane s , or by simply the focal ...
