CELESTIAL SAMPLE

Celestial Sample gives a simple representation of the 4 closest star with planet(s) within their habitable zone. It also displays the 80 closest star around our own sun. This simplified and yet precise celestial map is only describing the star in a 6 parsec radius aound the sun. In comparison, the Milky Way measures more than 30 000 parsec which stand for less than 0.000015% of the observable universe. Enjoy!

CELESTIAL MAP VALUES AND CONSTRUCTION

This celestial is a three dimensional map based on the Galactic Coordinate System with the Sun as its center. Each star is displayed regarding its own Galactic Longitudes, Latitude and Distance from the Sun.

Galactic Longitudes (G.Long) measures the angular distance eastward along the galactic equator from the galactic center measured here in degrees.

Galactic Latitude (G.Lat) measures the angular distance perpendicular to a plane parallel to the galactic equator, positive to the north, negative to the south, measured here in degree. In the current celestial map, Galatic Latitude has a 2 multiplication coefficient.

The distance from the Sun is measured in Parsec (pc.) which stands for 3.26 light years. At the current speed of the fastest man made object travelling space (Voyager 1 space probe), it would take approximately 50 000 years to travel a Parsec.

RED AND YELLOW DWARFS STARS

A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. Red and yellow dwarfs differ about their respectiv masses. Red dwarfs are considered today as the most common type of star but yet offers really low luminosity. The majority are so dim, they can not be seen by naked eyes. In the current celestial only the yellow dwarfs, alike our own sun, posses enought magnitude (brightness) to be observed.

STAR WITH PLANET(S) WITHIN ITS CIRCUMSTELLAR HABITABLE ZONE

The circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure, possibly sustaining condition for life to develop. Those four star or star system amoung the 80 closest starfs are today the only ones providing one or several planets within the circumstellar habitable zone. Travelling to those 4 stars would take between 60 000 years for the closest and 350 000 years for the farthest one.

HEIHGHTY CLOSEST STAR

These are the 80 closest stars to our sun within a 6 parsec range. The majority of those stars are red dwarfs main sequence stars. Traveling to the closest would take approximately 40 000 years, the farest about 300 000 years.
Position of each star soon to be displayed.

SIMPLE RANDOM SAMPLE

In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other subset of k individuals. This process and technique is known as simple random sampling. A simple random sample is an unbiased surveying technique.
