These objects are now well known to modern astronomers to be among the brightest and most striking gaseous nebulae, star clusters, and galaxies.
Objects on Messier's list are still referred to by their "Messier number".
For example the Andromeda Galaxy, the 31st object on the list, is known as M31.

  Solar System / Planets K-12 Experiments for Lesson Plans & Science Fair Projects
The inner solar system was too warm for volatile molecules like water and methane to condense, and so the planetesimals which formed there were relatively small (comprising only 0.6% the mass of the disc) and composed largely of compounds with high melting points, such as silicates and metals.
This great mass of up to a trillion icy objects, currently hypothetical, is believed to be the source for all long-period comets and to surround the solar system like a shell from 50,000 to 100,000 AU beyond the Sun, or almost a quarter the distance to the next star system.
The immediate galactic neighborhood of the solar system is known as the Local Fluff, an area of dense cloud in an otherwise sparse region known as the Local Bubble, an hourglass-shaped cavity in the interstellar medium roughly 300 light-years across.

 Pluto - Crystalinks
Mass and Size Astronomers, assuming Pluto to be Lowell's Planet X, initially calculated its mass on the basis of its presumed effect on Neptune and Uranus.
In 1955, Pluto was calculated to be roughly the mass of the Earth, with further calculations in 1971 bringing the mass down to roughly that of Mars.
Among the objects of the Solar System, Pluto is not only smaller and much less massive than any planet, but at less than 0.2 lunar masses it is also smaller than seven of the moons: Ganymede, Titan, Callisto, Io, the Moon, Europa and Triton.

 Solar system   (Site not responding. Last check: )
In broad terms, the solar system consists of the Sun, eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor planets, planetoids, meteoroids, planetesimals or, in the case of Pluto, planets).
In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a results, the inner planets formed minerals and are rocky, and the outer planets were massive enough to attract gases.
Before the discovery of 2060 Chiron and the trans-Neptunian objects, the term "minor planet" was a synonym for asteroid, but many people now prefer to restrict the use of "asteroid" to refer to rocky bodies of the inner solar system.

The boundary between the solar system and interstellar space-called the heliopause-is estimated to occur near 100 AU.
Through the end of the 1980s, this solar system was the only planetary system known to exist, although a number of relatively nearby stars had been found to be encircled by swarms of orbiting material of indeterminate size or to be accompanied by suspected brown dwarfs.

This is a list of solar system objects by radius, arranged in descending order of mean volumetric radius.

The ordering is not the same as the order of a list of solar system objects by mass because some objects are denser than others.

Because Pluto is also the smallest planet in our solar system and has a highly eccentric orbit (which takes it inside the orbit of Neptune) there has been some debate regarding whether Pluto should be classified as a planet (see below for details).
In the following decades estimates of Pluto's mass and diameter were the subject of debate as telescopes and imaging systems improved.
Sedna could be the largest object yet discovered in the solar system since Pluto in 1930.

Trans-Neptunian objects are considered to be minor planets, so the question arose whether to consider Pluto to be one too.
Some argue that an astronomical object more than about 360 km in diameter, at which point the object has a tendency to become round under its own gravity, should be known as a major planet; this would include several moons and a handful of asteroids.
This caused its discoverers to call it as the "10th planet" of the solar system, although there is no consensus yet on whether to call it a planet, and others consider the new discovery to be the strongest argument yet for demoting Pluto to the status of a minor planet.
