  2. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    The largest such scale model, the Sweden Solar System, uses the 110-meter (361-foot) Avicii Arena in Stockholm as its substitute Sun, and, following the scale, Jupiter is a 7.5-meter (25-foot) sphere at Stockholm Arlanda Airport, 40 km (25 mi) away, whereas the farthest current object, Sedna, is a 10 cm (4 in) sphere in Luleå, 912 km (567 mi ...

  3. Analemma - Wikipedia

    en.wikipedia.org/wiki/Analemma

    In astronomy, an analemma (/ ˌænəˈlɛmə /; from Ancient Greek ἀνάλημμα (analēmma) 'support') [a] is a diagram showing the position of the Sun in the sky as seen from a fixed location on Earth at the same mean solar time, as that position varies over the course of a year. The diagram resembles a figure eight.

  4. Spherical coordinate system - Wikipedia

    en.wikipedia.org/wiki/Spherical_coordinate_system

    In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three real numbers: the radial distance r along the radial line connecting the point to the fixed point of origin; the polar angle θ between the radial line and a given polar axis; [a ...

  5. Thin disk - Wikipedia

    en.wikipedia.org/wiki/Thin_disk

    For comparison, the Sun is 8 kiloparsecs (26 kly) out from the center. The thin disk contributes about 85% of the stars in the Galactic plane [ 3 ] and 95% of the total disk stars. [ 2 ] It can be set apart from the thick disk of a galaxy since the latter is composed of older population stars created at an earlier stage of the galaxy formation ...

  6. Milky Way - Wikipedia

    en.wikipedia.org/wiki/Milky_Way

    The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [7][8][9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.

    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.

  8. Earth's orbit - Wikipedia

    en.wikipedia.org/wiki/Earth's_orbit

    Earth orbit (yellow) compared to a circle (gray) Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), or 8.317 light-minutes, [1] in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million ...
