close to Teilhard de Chardin's planetization, in which «[mankind, born on this
planet and spread over its entire surface, come [s] gradually to
form round its earthly matrix, a single, major, organic unity, enclosed upon itself.4 Thus the globalization of humankind could lead to the formation of a new kind of living entity — a social organism — on the same cosmic principle as that by which atoms join to
form molecules, molecules join to
form mega-molecules, mega-molecules unite to
form living cells, and innumerable cells constitute an organism.

To begin with, they orbited
close to the plane of the ecliptic in the same direction as the

The
planet [a hot Jupiter] was too
close to its sun to have
formed there, and this implied something had to have migrated inward.
Trilling says the triple - star
planet could belong to a class that
formed in a different way, maybe even
close to the star.
Churchill assumes that

formed from the gas that is torn off a star when another star passes
close to it — a model suggested by astrophysicist James Jeans in 1917, which has since been ruled out.
The discoveries fill in details about how
planets form and bring researchers even
closer to the ultimate prize: «We're on our way to finding an extrasolar earth,» says Barbara McArthur of the University of Texas at Austin.
Jupiter's core might have
formed close to the sun and then meandered through the rocky
planet construction zone.
Most solar systems might
form with
planets squished even
closer together.
Ghost - like particles that were first created in the instant following the Big Bang, antineutrinos and their partner neutrinos travel at
close to the speed of light and are notoriously difficult to observe as they move through space, passing through
planets, star systems, and galaxies with scant interactions with other
forms of matter.
On February 25, 2008, a team of astronomers released a paper on simulation results which support the conclusions of previous studies that multiple -
planet systems could have
formed in
close orbits around both heavy - element rich, Alpha Centauri A and B.
How could a
planet be so
close to its parent star — it seemed very unlikely that it could
form there — and was such a
planet stable against evaporation by stellar radiation?
Alternatively, the
planet could be evidence against the migration theory, suggesting that giant
planets can in fact
form close in to their stars.
The modelling suggested that a Neptune - like
planet actually
formed much
closer to Vega and was pushed by a Jupiter - like
planet in an inner orbit out to its current wide orbit around 80 AUs away from Vega over about 56 million years, sweeping many comets out with it and causing the dust disk to become clumpy (Mark C. Wyatt, 2003).
If you dream of one day interacting with aliens, you better hope that their home
planet is relatively
close by — but then again, perhaps disgusting enormity of the universe is the only reason that another intelligent life -
form hasn't yet blown our fair Earth to smithereens.
Cooler dust, for instance, could allow larger
planets to
form quite
close to their parent star.
Davies says
planets that lie
close to their stars may have been bigger when they were first
formed.
In stark comparison, HAT - P - 26b has a metallicity of just 4.8 times that of the Sun, suggesting that not only is it
closer to the gas giants in composition but also that it likely
formed closer to its host star than the
planets of a similar size in our own system.
It is commonly believed that the
planets Uranus and Neptune migrated out to their present orbits after
forming closer to the sun and then gravitationally interacted with smaller bodies.
Oddly enough, Oort Cloud objects were probably
formed in a region of the proto - planetary disk that was located
closer to the Sun than the Edgeworth - Kuiper Belt objects that persist in the orbital plane of the
planets (ecliptic) to this day.
