Could Psyche be the core of the planetesimal body that struck Earth and resulted in the formation of the Moon? Colton Brooks ...

These meteorites would have been the fractured remains of early "unmelted asteroids," a type of planetesimal. Planetesimals ...

NASA is constantly working on new projects that expand our horizons in space and on Earth. From putting men back on the moon ...

(Planetary nebula have nothing to do with planets; the term is a historical misnomer.) Planetesimal—One of the family of asteroid-sized bodies that first condensed out of the disk of the solar ...

These are the Nebular Hypothesis of Laplace, the Planetesimal Hypothesis of Chamberlin and Moulton, and the Capture Theory of See. Darwings theory of Tidal Friction is scarcely a distinct ...

Zinc in meteorites reveals Earth's essential volatiles came from unmelted asteroids, crucial for life. This insight may guide the search for life on other planets. Researchers have analyzed the ...

On the planetesimal hypothesis, the two internal zones find a ready explanation. It is supposed that the earth began as a nebulous knot, and that it has grown up to its present mass by the capture ...

Using these measurements, and simulations of the physics of dust and planetesimal collisions, planetary scientists and astronomers have established that the dust-to-protoplanet process takes tens of ...

"Theoretical models of planetesimal and planet formation predicted that objects like this should be out there. And the very first Kuiper Belt planetesimal that we visit turns out to be one of them ...

As a result of vaporization, they lost volatiles. Another kind of planetesimal was born later and thus held on to their volatiles. As the team studied zinc in different meteorites and traced their ...

The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under ...
