  2. Celiac plexus - Wikipedia

    en.wikipedia.org/wiki/Celiac_plexus

    The celiac plexus is often popularly referred to as the solar plexus. In the context of sparring or injury, a strike to the region of the stomach around the celiac plexus is commonly called a blow "to the solar plexus". In this case it is not the celiac plexus itself being referred to, but rather the region around it.

  3. Heliosphere - Wikipedia

    en.wikipedia.org/wiki/Heliosphere

    Because the solar wind and the ISM are both fluid, the heliosphere's shape and size are also fluid. Changes in the solar wind, however, more strongly alter the fluctuating position of the boundaries on short timescales (hours to a few years). The solar wind's pressure varies far more rapidly than the outside pressure of the ISM at any given ...

  4. Water on terrestrial planets of the Solar System - Wikipedia

    en.wikipedia.org/wiki/Water_on_terrestrial...

    The best constraints for accreted H 2 O are determined from non-atmospheric H 2 O, as the D/H ratio of the atmospheric component may be subject to rapid alteration by the preferential loss of H [22] unless it is in isotopic equilibrium with surface H 2 O. Earth's VSMOW D/H ratio of 1.6×10 −4 [7] and modeling of impacts suggest that the ...

  5. Origin of water on Earth - Wikipedia

    en.wikipedia.org/wiki/Origin_of_water_on_Earth

    The boundary of the region where ice could form in the early Solar System is known as the frost line (or snow line), and is located in the modern asteroid belt, between about 2.7 and 3.1 astronomical units (AU) from the Sun. [23] [24] It is therefore necessary that objects forming beyond the frost line–such as comets, trans-Neptunian objects ...

  6. Planetary surface - Wikipedia

    en.wikipedia.org/wiki/Planetary_surface

    Liquid water as surface, beside on Earth, has only been found, as seasonal flows on warm Martian slopes, as well as past occurrences, and suspected at the habitable zones of other planetary systems. Surface liquid of any kind, has been found notably on Titan, having large methane lakes, some of which are the largest known lakes in the Solar System.

  7. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also

  8. Solar Plexus - Wikipedia

    en.wikipedia.org/wiki/Solar_Plexus_(disambiguation)

    The celiac plexus (or solar plexus) is a complex network of nerves located in the abdomen. Solar plexus or Solar Plexus may also refer to: The solar plexus chakra in Hinduism, see Manipura

  9. Planetary core - Wikipedia

    en.wikipedia.org/wiki/Planetary_core

    The internal structure of the inner planets. The internal structure of the outer planets. A planetary core consists of the innermost layers of a planet. [1] Cores may be entirely liquid, or a mixture of solid and liquid layers as is the case in the Earth. [2]
