rigel compared to the sun

The spectrum of Rigel (the star in the knee of Orion) peaks in the short-wavelength end of the visible spectrum. hotter and whiter. If Rigel were as close as Sirius, the brightest star visible to the eye (and only about 8.6 light-years away), Rigel would shine much more brilliantly than Venus, our sky’s brightest planet. New York, Rigel, a blue supergiant star, is 18 times more massive than the sun and 74 times its size. hotter and redder.D. The surface area of a sphere is proportional to radius squared, so square rooting this area gives a radius of 98.8 times that of the Sun. "Astronomers have made several observations of Rigel in recent years. [Full story] The star has a radius almost 79 times that of the Sun and an estimated mass of 21 solar masses. The Rigel's solar mass is 21.00 times that of our star, the Sun. Since Rigel is 64,000 times brighter than the Sun, the surface area must be 64,000/6.55 = 9770 times that of the Sun. Compared with the Sun, Rigel is. Big is bigger than we can ever imagine. It would take a passenger jet 1,100 years to fly round it once.Being much further from its core though, the surface temperature of VY Canis Majoris is cooler than our sun at around 3,000C - compared to our star's 5,600C.VY Canis Majoris is also near the end of its lifespan and is expected to explode as a supernova in the next 100,000 years - our's has around 5bn years to go before it burns out and envelopes the Solar System.After VY Canis Majoris explodes its remaining core will be big enough to create a black hole.French astronomer Jerome Laland was the first to record VY Canis Majoris in 1801.Emma Wride of the AstroCymru Project, which aims to inspire the next generation of astronomers, revealed the video at the astronomy show.She said: "It is a relatively recent discovery in the Milky Way. Rigel, too, is barely even visible compared to Canis Majoris. It also has two known companions, Rigel B and Rigel C. The star is about 870 light-years from the sun and 47,000 times as luminous, according to Encyclopedia Britannica. We only see a minuscule piece of the universe. Rigel Mass. 1.6^4 = 6.55x the Sun's brightness per unit area. It's in the name of a number of planets in the "Star Trek" universe, is mentioned in "The Hitchhiker's Guide to the Galaxy," and is also featured in a number of other novels, computer games and comic books.The name comes from an Arabic phrase, "Rijl Jauzah al Yusrā," which means, "The left leg of the Jauzah," according to Richard Hinckley Allen's book "Star Names: Their Lore and Meaning" (Dover Publications, 2013). "Each big object in space is part of a much larger structure - the large-scale structure of the visible universe. Each big object in space is part of a much larger structure - the large-scale structure of the visible universe. If you need the diameter of the star, you just need to multiple the radius by 2. Refraction is the. NY 10036. Size comparison between sun and the blue giant star Rigel (beta Ori), which is approx. The phrase is also sometimes translated as "The left leg of the giant," referring to the Rigel is close to zero magnitude in Earth's sky, making it a Rigel has two distant stellar companions, Rigel B and Rigel C — a binary system. bend around corners and edges.
