Pollux is a bright star in the constellation of Gemini and it is 34 light years away from our planet. The mass is 1.86 Solar mass or 2.3 times heavier than Jupiter

Arcturus
Arcturus is a bright star in the constellation bootes and it is 110x more luminous than Sun and the power is 180x more than Sun. the diameter is 22 millions miles and the mass is 1.5 Solar mass

Aldebaran
Aldebaran is a giant star in the constellation of Taurus and it could be find 65.1 light years from earth. The luminosity is 150x than the Sun, the diameter is 44.2 time than Sun (61 million kilometers) and the mass is 1.7 solar mass

Aldebaran-Rigel- Betelgeuse-Antares

Rigel
Rigel is located at the constellation Orion or around 700 and 900 light-years from earth. The blue super-giant star is 85,000 brighter than Sun, the diameter is 5.45 x 1010 meters and the mass is 17 Solar mass

Betelgeuse
Betelgeuse is our next biggest stars. The mass is 18–19 solar mass. The luminosity is 180,000 brighter than he Sun

Antares
Antares is a star that is located 600 light-years from earth and it is one of the biggest star in our milky way galaxy. The luminosity is 65,000x than sun and the mass is 15-18 Solar mass

Antares-S Doradus-KY Cygni-VV Cephei

S doradus
S Doradus has 100–380 solar diameter ( radius of the sun). the mass is 45 solar mass and the star could be found in Constellation of Dorado or 169,000 light years from Earth

KY Cygni
The diameter of KY Cygni is around 1,420–2,850 solar diameter. The star is 300,000 brighter than sun and it could be found 5,000 light-years from Earth on the constellation Cygnus

VV Cephei
VV Cephei is the 2nd biggest stars that is found in the universe and the diameter is 1,600–1,900 Solar diameter. The mass is around 100 solar mass and it could be found in the Constellation Cepheus or 2,400 light years away from Earth

Vy canis majoris compared with sun

VY Canis Majoris

VY Canis Majoris is very huge star in the Constellation Canis Major. The diameter is 1800-2100 solar diameter or 2.7 billion km across/1.7 billion miles. From this picture. You can see how big the star is. The star is only 4,900 light-years from Earth and the mass is around 30-40 solar mass. It is so big so that we will require 7×1015 Earths to fill the whole volume of VY canis majoris

Sizes Comparison

Technology is changing and improving so It is possible that we will find bigger sun than Most amazing planet and stars above

Recalculating the Distance to Interstellar Space

Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought. The findings are detailed in this week's issue of the journal Nature.

Data from Voyager's low-energy charged particle instrument, first reported in December 2010, have indicated that the outward speed of the charged particles streaming from the sun has slowed to zero. The stagnation of this solar wind has continued through at least February 2011, marking a thick, previously unpredicted "transition zone" at the edge of our solar system.

"There is one time we are going to cross that frontier, and this is the first sign it is upon us," said Tom Krimigis, prinicipal investigator for Voyager's low-energy charged particle instrument and Cassini's magnetospheric imaging instrument, based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md.

Krimigis and colleagues combined the new Voyager data with previously unpublished measurements from the ion and neutral camera on Cassini's magnetospheric imaging instrument. The Cassini instrument collects data on neutral atoms streaming into our solar system from the outside.

The analysis indicates that the boundary between interstellar space and the bubble of charged particles the sun blows around itself is likely between 10 and 14 billion miles (16 to 23 billion kilometers) from the sun, with a best estimate of approximately 11 billion miles (18 billion kilometers). Since Voyager 1 is already nearly 11 billion miles (18 billion kilometers) out, it could cross into interstellar space at any time.

"These calculations show we're getting close, but how close? That's what we don't know, but Voyager 1 speeds outward a billion miles every three years, so we may not have long to wait," said Ed Stone, Voyager project scientist, based at the California Institute of Technology in Pasadena.

Scientists intend to keep analyzing the Voyager 1 data, looking for confirmation. They will also be studying the Voyager 2 data, but Voyager 2 is not as close to the edge of the solar system as Voyager 1. Voyager 2 is about 9 billion miles (14 billion kilometers) away from the sun.

Launched in 1977, the Voyager twin spacecraft have been on a 33-year journey. They are humanity's farthest working deep space sentinels enroute to reach the edge of interstellar space. The Voyagers were built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., which continues to operate both spacecraft. The Voyager missions are a part of the NASA Heliophysics System Observatory, sponsored by the Heliophysics Division of NASA's Science Mission Directorate in Washington.
