  2. Chemical energy - Wikipedia

    en.wikipedia.org/wiki/Chemical_energy

    Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...

  3. Planetary differentiation - Wikipedia

    en.wikipedia.org/wiki/Planetary_differentiation

    The Moon's density is substantially less than that of Earth, due to its lack of a large iron core. [3] On Earth , physical and chemical differentiation processes led to a crustal density of approximately 2700 kg/m 3 compared to the 3400 kg/m 3 density of the compositionally different mantle just below, and the average density of the planet as a ...

  4. Moon - Wikipedia

    en.wikipedia.org/wiki/Moon

    The Sun is much larger than the Moon, but it is the vastly greater distance that gives it the same apparent size as the much closer and much smaller Moon from the perspective of Earth. The variations in apparent size, due to the non-circular orbits, are nearly the same as well, though occurring in different cycles.

  5. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers classify it as a G-type main-sequence star. The largest objects that orbit the Sun are the eight planets.

  6. Sun - Wikipedia

    en.wikipedia.org/wiki/Sun

    The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.

  7. Astronomy - Wikipedia

    en.wikipedia.org/wiki/Astronomy

    One of the oldest fields in astronomy, and in all of science, is the measurement of the positions of celestial objects. Historically, accurate knowledge of the positions of the Sun, Moon, planets and stars has been essential in celestial navigation (the use of celestial objects to guide navigation) and in the making of calendars.

    Theoretical total mass–energy of the Moon [269] [270] 10 40 1.61×10 40 J Baryonic mass-energy contained in a volume of one cubic parsec, on average. [265] [271] 10 41 2.276×10 41 J: Gravitational binding energy of the Sun [272] 5.3675×10 41 J: Theoretical total mass–energy of the Earth [273] [274] 10 43 5×10 43 J

  9. Heliophysics - Wikipedia

    en.wikipedia.org/wiki/Heliophysics

    Heliophysics combines the science of the Sun, corona, heliosphere and geospace, and encompasses a wide variety of astronomical phenomena, including "cosmic rays and particle acceleration, space weather and radiation, dust and magnetic reconnection, nuclear energy generation and internal solar dynamics, solar activity and stellar magnetic fields ...
