Planetesimals, from which the planets were originally formed, are sub-planetary bodies that accreted during the first years of the solar system and that no longer exist.
Until recently, the solar system was the only known example of a planetary system, although it was widely believed that other comparable systems did exist.

In broad terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, composed of icy objects.
The dimensions of the solar system are specified in terms of the mean distance from Earth to the Sun, called the astronomical unit (AU).
The solar system was the only planetary system known to exist around a star similar to the Sun until 1995, when astronomers discovered a planet about 0.6 times the mass of Jupiter orbiting the star 51 Pegasi.

 Sol
Finally, Sol has about 50 percent more heavy elements than other stars of its age and type, but only about a third of their variation in brightness, which is also fortunate because heavy elements are essential to make planets like Earth and large stellar flare-ups can harm planetary life with hard radiation.
Sol is becoming hotter and brighter as fusion of helium "ash" becomes more statistically common with the gradual depletion of hydrogen at its core, which may be half helium after 4.6 billion years of hydrogen fusion.
Sol is expected to become another 10 percent brighter over the next 1.1 billion years, and so Earth may become too uncomfortably hot for even microbial life in another 500 to 900 million years.

 Oort Cloud & Sol b?
In 1950, Jan Hendrik Oort (1900-1992) inferred the existence of the Oort Cloud from the physical evidence of long-period comets entering the planetary system.
During the first 100 million years of the System's birth, small planetary bodies that formed near the developing giant planets would have been ejected from their neighorhood through gravitational encounters (Levison et al, 1999; and Dones et al, 1998).
Hence, either the object formed independently from fragmentation of the original Solar nebula, or the object was ejected from another star system and subsequently captured by the Sun (possibly as early as Sol was born in the crowded environs of its original star-forming cluster).

 SOL Book 6, Chapter 9, John Stuart Mill, A System of Logic
As might be expected, the most imperfect part of those branches of social inquiry which have been cultivated as separate sciences is the theory of the manner in which their conclusions are affected by ethological considerations.
The omission is no defect in them as abstract or hypothetical sciences but it vitiates them in their practical application as branches of a comprehensive social science.
In statistics it is evident that empirical laws may sometimes be traced, and the tracing them forms an important part of that system of indirect observation on which we must often rely for the data of the Deductive Science.

 Introduction and FAQ
A "planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
But on a smaller body, like some of the smaller moons and asteroids, the force of gravity is much weaker and so rock can support relatively large "mountains".

Vulcanoids are hypothetical asteroids that may orbit in a dynamically stable zone between 0.08 and 0.21 astronomical units from the Sun, well within the orbit of Mercury.
They take their name from the hypothetical planet Vulcan, which eighteenth-century astronomers fruitlessly searched for to explain the excess precession of Mercury's perihelion.
Nevertheless, it is thought Vulcanoids could exist because the region of space being searched is gravitationally stable, and all similarly stable regions of the solar system have been found to contain objects.

 Nemesis (star) - Art History Online Reference and Guide
Nemesis is the name given to a hypothetical red dwarf star, magnitude between 7 and 12, orbiting the Sun at a distance of about 50,000 to 100,000 AU, somewhat beyond the Oort cloud.
Nemesis' existence was proposed by Richard A. Muller in 1984 ( Nature, vol 308, pp 715-717, 1984) to explain an apparent 26-million year cycle in the occurrence of mass extinctions on Earth as noted by Raup and Sepkoski.
According to the theory, Nemesis periodically (roughly every 26 million years), passes through a denser region of the Oort cloud, disrupting the orbits of comets, and sending millions into the inner solar system and potential collision with the Earth.
