The Solar System, and the other stars/dwarfs listed here, are currently moving within (or near) the Local Interstellar Cloud, roughly 30 light-years (9.2 pc) across. The Local Interstellar Cloud is, in turn, contained inside the Local Bubble, a cavity in the interstellar medium about 300 light-years (92.0 pc) across.
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M , K , F , G , A , B and O . It may be later expanded to other types, such as S , D or C .
In 2013 researchers discovered that asymmetrical fullerenes formed from larger structures settle into stable fullerenes. The synthesized substance was a particular metallofullerene consisting of 84 carbon atoms with two additional carbon atoms and two yttrium atoms inside the cage.
The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups. This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association ...
Only very stable fullerenes such as [Sc 3 N] +6 @[C 80] −6 pass through the column unreacted. In Ce 2 @C 80 the two metal atoms exhibit a non-bonded interaction. [4] Since all the six-membered rings in C 80-I h are equal [4] the two encapsulated Ce atoms exhibit a three-dimensional random motion. [5]
Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [102]
