    But, the problem with this further "test" is WHEN. When our solar system was young no planet would have passed this test. This said, the definition of "planet" is something philosophical that you cannot prove using astronomical observations. In the space objects don't show labels saying "planet" or "asteroid" or "comet" or "dwarf planet".

  3. Pluto and Eris should be considered planets - History Forum

    historum.com/t/pluto-and-eris-should-be-considered-planets.195957

    Eris and Plutos mass is 10^22 (along with our Moon, Io, Europa and Triton). While Eris and Pluto are on the low end of 10^22, the 10^21 dwarf planets are on the low end of 10^21 with the biggest of the bunch Haumeas mass being 4 times that out of 10. Another thing that seperates Pluto and Eris from the other dwarf planets are their large moons ...

  4. Phaeton (hypothetical planet) | History Forum

    historum.com/t/phaeton-hypothetical-planet.132851

    The hypothetical planet was named for Phaethon, the son of the sun god Helios in Greek mythology, who attempted to drive his father's solar chariot for a day with disastrous results and was ultimately destroyed by Zeus. I suspect it may still be valid. even though it's original promoters, have been discredited.

    This would be as ludicrous as concluding that planets do not exist because astronomers disagree over whether or not Pluto is a planet (when I was a child, I was taught that there were nine planets in our solar system, of which Pluto was the outermost).

  6. Armour: chain/mail vs scale vs lamellar vs plate - History Forum

    1. Simple to make. It is one of the first metal armor type made in history. 2. Layering of the scale provide double thickness of the scale plate. 3. Easy to repair without furnace or metal tool (when the plates are sewn to backing, not riveted). - Bad. 1.

    There wasn't even strict agreement on which Gods were in that shortlist! Sometimes Hestia is, sometimes Dionysus took her place. And it's far from clear that they all worshiped the same god even when the name was in common (see #2). There were also Gods that weren't Olympians: Hades / Pluto perhaps being the most famous.

    The advent of gunpowder in the 15th century changed the way Wars were waged, but it wasn't until the Napoleonic Era that artillery and individual firearms made "Total War" the new concept. A different approach to the study of War is found in Sun-Tsu's book , the Art of War. H.

  9. Height of European across the ancient and medieval times.

    It is difficult to imagine the Roman legionaries or the gladiators as (very) short men, but I guess that this was the case. By modern standards, the ancient men was short. Take the 2AD as an example: Mediterranean men average at 1.66,8; Central-western men averaged at 1.68,9 and North-eastern men averaged at 1.69,9.

  11. Ulysses S. Grant at Shiloh | History Forum - historum.com

    historum.com/t/ulysses-s-grant-at-shiloh.50774

    The only argument for a tie seems to be that Grant's casualties were rather high, compared to what had come before; of course, the fighting in Virginia would soon dwarf the casualties of Shiloh. Johnston and Beauregard's objective was to destroy Grant before he could be reinforced by Buell, and they clearly failed at that, even with a fifth of ...
