the planets in our solar system do, then gravity - darkening could have no effect at all.
There's an intriguing twist, too: Jayawardhana and others have shown that young brown dwarfs generally do not have massive protoplanetary disks of gas and dust, which means that if the new object is indeed a planet, it may not have formed the same way
planets in our solar system did.

in the early
solar system, but where
did all the large
planets receive the energy to boost them into much higher orbits?

planets and most of the asteroids
in the
solar system orbit the Sun
in the same direction because the
solar system emerged from a revolving cloud of dust and gas, most of the constituent objects of which continue to revolve as they
did before.
In previous studies, Martin Jutzi and Willy Benz, astrophysicist at CSH of the University of Bern and
PlanetS director, had already come to the conclusion that Chury
did not receive its two - component structure when our

in two different places
in our
solar system, it could presumably
do so a million times, or a billion, on
planets throughout our galaxy — because, again, life misses no opportunity.

in the
solar system does not have a tail, new observations show.
The exoplanet (a
planet in another
solar system) is about six times the mass of Jupiter and orbits about 40 percent closer to its star, dubbed HD 102272, than Earth
does around the sun.
The two gas giant
planets did a gravitational dance with the sun and each other that sent them hurling
in then back out to the outer
solar system.
When the first extrasolar
planets were found, they seemed so different from those
in our own
solar system, so the question quickly morphed to «How
does our
solar system compare with other
solar systems?»
I used to wonder why our
solar system didn't have more
planets, but then people who run
solar system simulations tried to drop more
planets in and found that all the other
planets became gravitationally unstable.
Over a simulated interval of 200 million years, the inner
planet slowly migrated even farther inward to become a «warm Jupiter» orbiting its parent star at about the same distance Mercury
does in our
solar system, the researchers report online today
in Science.
He
does worry that on other
planets that don't receive light energy from a sun but still get bombarded with GCRs — such as free floating rogue
planets not tied to any
solar system — temperatures would dip too low and freeze life
in its tracks.
Simulating the assembly of the
solar system around 4.56 billion years ago, researchers propose that the Red
Planet didn't form
in the inner
solar system alongside the other terrestrial
planets as previously thought.
Viewed from a
planet at Earth's orbital distance around Alpha Centauri A, stellar companion B would provide more light than the full Moon
does on Earth as its brightest night sky object, but the additional light at a distance greater than Saturn's orbital distance
in the
Solar System would not be significant for the growth of Earth - type life.
So classifying it as a dwarf
planet explains how it interacts (or, really, how it doesn't interact) with other objects
in the
solar system.
