Planetesimals
Explanation:
The planet formation theory from planetesimals (1941)f is attributed
to Victor Safronov
Small space bodies growing in size by accretion process that is
initially non-gravitational and includes emission by thermal
photons includes emission.
Further growing in size is attributed to central attraction that keep
the constituents that become embedded together.
The consequent radial attraction from the center gives a near-
spherical surface to the planet thus formed, with almost all A - Z
elements.
