A Sun-moon-earth model for teaching comprises a pedestal (1), the sun (2), the earth (3), the moon (4), a connecting rod (5) and a transmission mechanism; the earth (3), the moon (4) and the transmission mechanism are all arranged on the connecting rod (5); the connecting ...
The synestia model of Lock et al. (2018) would likely yield values similar to the impact-fission model, |δfT| < 20%. Yet another model for the Moon-forming impact is the hit-and-run model, in which half of a larger (∼0.2−0.3 M⊕) Theia is accreted to Earth and half...
KT Sun,CL Lin,SM Wang 摘要: The relative positions of the sun, moon, and earth, their movements, and their relationships are abstract and difficult to understand astronomical concepts in elementary school science. This study proposes a three-dimensional (3-D) virtual reality (VR) model named ...
The incredible real-time rendered the 3D Earth image. The powerful Apple Metal engine can make that amazing 3D Earth model and optic effects only. Whole earth a…
Probably this scenario is in favour of the Darwin's hypothesis about originating the moon by its separation from the earth. Too much short time scale of the evolution in this model might be enlarged if the dissipative Q factor had somewhat larger values in the past than in the present epoch...
In LOWTRAN7, direct or scattered light from either the Sun or the Moon can be calculated. The Sun's irradiance is interpolated from a spectrum, and an orbit correction is applied to compensate for Earth's orbital eccentricity. The Moon's irradiance is calculated using a mathematical mode...

The other approach is to physically model the earth and moon within the wristwatch as in Ulysse Nardin’s fabulous Tellurium watch. One of a trio of astronomical watches designed by watchmaker-inventor Ludwig Oeschlin in the late 80s, the Tellurium ...
sometimes called the Big Whack model or the ring ejection theory, at a young age Earth was sideswiped by a celestial object as large or larger than Mars. As a result of that collision, a ring of crustal matter was spewed into space, and over time the matter in this ring agglomerated to...
