ORIGIN OF SOLAR SYSTEM
TWO MODELS
GEOCENTRIC MODEL
it is earth-centered, which places the Earth as the center of the universe
-
the planets, the Sun and the stars revolve around Earth
-
NEBULAR THEORIY
.
These clouds are gravitationally unstable, and
matter coalesces within them to smaller denser clumps, which then rotate, collapse, and form stars
-
Simply put, this theory states that planets form because of the dust particles that came from the Sun.
PROTOPLANET THEORY
it is a rapidly rotating nebulas will develop large whirlpools or vortexes at various places on the
disk of nebular material
-
it is a whirling cloud of massive gas or dust that becomes a planet by condensation during formation of a solar system.
it can also come from the vicinity of an asteroid, then, collision happens and form celestial bodies or planet.
PLANETESIMAL THEORY
-
The smaller masses quickly cooled to become solid bodies, then it is gradually pulled together by gravity to form small chunks called planetesimals.
T. C. proposed that a star once passed near the Sun, pulling away from it matter that later condensed and formed the planets
This theory states that the planets were formed by the accumulation of extremely small bits of dust particles that revolved around the sun.
HELIOCENTRIC THEORY
it is Sun-centered, which the Sun is the center of the universe
-
GENERAL PRINCIPLES
-
All the spheres rotate around the sun, which is near the center of the universe
-
Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.
