List of nearest stars
This list of the nearest stars to Earth is ordered by increasing distance out to a maximum of 5 parsecs (16.3 light years). Stars with an apparent magnitude greater than 6.

The nearest stars do have observable motions that are a consequence of their motion through the galaxy and the motion of the Earth around the Sun; but these motions are observable only with fine instruments.

Notes

Light from even the nearest stars takes several years to reach us, so we see them as they were a few years in the past. As telescopes improve, fainter and more distant stars and galaxies can be seen.
Sirius also belongs to the nearest stars with a distance of just 8.7 light years. This white star has a companion of 8th mag at a distance of approximately 10''. The companion, a white star usually called Sirius B, is not easy to resolve.
Parallax methods can then be applied (using the Earth's orbit as a baseline) to obtain the distances to the nearest stars. An important step in the distance ladder is the determination of the distance to the Hyades cluster.
Messages have been attached to the Pioneer and Voyager spacecraft, but they will take thousands of years to reach the nearest stars.
8 light years, Sigma Dra is one of the nearest stars to the Earth, ranking within the closest 100 star-systems (wherein doubles and multiples are considered as units), Alsufi coming in at number 65.
Nearest Stars is a handy list of the 50 nearest stars with several key properties such as parallax, spectral type and apparent and absolute magnitudes listed in table form. Follow the link to a second table listing the 50 Brightest Stars.
Astronomers derive distances to the nearest stars (closer than about 100 light-years) by a method called stellar parallax. This method that relies on no assumptions other than the geometry of the Earth's orbit around the Sun.
The parallax method of determining these distances can be applied only to a few thousand of the nearest stars. A special class of stars exists, the Cepheid variables, which vary in brightness in periods that depend on their intrinsic intensities.
In the original version of the theory, the Oort cloud extended tens of thousands of times farther from the Sun than the Earth, a significant fraction of the way to the nearest stars.
Parallax measures can be obtained only for the nearest stars. The nearest star, Proxima Centari, is at a distance of 1.31 pc, which means that even the nearest star shows a parallax shift of less than one arc second.
The problem with parallax is that even the nearest stars are so far away that the jump made as the Earth changes its position by 300 million kilometers is very small. The nearest star will only move less than one arc second.
Large orbiting telescopes may soon be able to detect Jupiter-sized planets orbiting the nearest stars, but even those huge planets will be barely visible.
Barnard's Star, one of the nearest stars to the Solar System (the only stars closer are the Alpha Centauri binary star system and Proxima Centauri), lies in Ophiuchus.
Our best bet may be to build an enormous colony-type spacecraft capable of sustaining a crew for the decades necessary to reach even the nearest stars.
Using parallax, we can only determine the distances to a few thousand of the nearest stars. Some of these stars are Cepheids.
(a) The brightest star in the constellation Canis Minor and one of the nearest stars, lying just 11.4 light-years from Earth. Procyon is the eighth brightest star in the night sky.
Sirius is one of the nearest stars. See this German site for a nice three-dimensional representation of our nearby neighbor stars.
Sirius B or The Pup ...
It is one of the nearest stars to our solar system, only 14.8 light-years distant from the Sun. It is classified as a flare star, which means that it can unexpectedly become more luminous over short periods.

It is also one of the nearest stars, lying at a distance of 8.7 light-years, so that it has been studied extensively. From an analysis of its motions, F. W.
Only in 1838 were definite parallaxes measured for some of the nearest stars--for Alpha Centauri by Henderson from South Africa, for Vega by Friedrich von Struve and for 61 Cygni by Friedrich Bessel.

The nearest stars are light years away, while the Moon is about a billion times nearer. Collisions between stars are believed to happen, but they must be very infrequent.
is a tremendous advantage to be gained from combining data from the AAT and Keck telescopes, two world-class observatories, and it's clear that we'll have an excellent shot at identifying potentially habitable planets around the very nearest stars ...
farther away an object is, the larger the baseline needs to be. This is why the diameter of the Earth's orbit around the Sun is used as the baseline for measuring stellar parallaxes. Even so, this method can only be used for the very nearest stars.
