The number of A. The star's Galacto-Centric Distance is 7, The catalogue was started by the American doctor and has been expanded on over the years. The star is catalogued in the Tycho-2 star catalogue as TYC The catalogue lists 2 millions stars and its homepage is E. Mimosa Travel Time The time it will take to travel to this star is dependent on how fast you are going. A note about the calculations, when I'm talking about years, I'm talking non-leap years only days.
The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch , Pluto was still a planet. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound.
Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. The star is a pulsating Beta Cephei variable type which means that its size changes over time.
The Variable Type is usually named after the first star of that type to be spotted. Mimosa brightness ranges from a magnitude of 1. The smaller the magnitude, the brighter the star. The source of the information if it has a Hip I. Hipparcos was a E. The items in red are values that I've calculated so they could well be wrong. The information was obtained as of 12th Feb Below is a tabular view of the star facts with the values of the Sun on the right so you can compare against our own star, the Sun.
The Sun is our nearest star and it is what keeps us warm and gives us light as we complete one orbit in If you want to see the comparison between Mimosa and our star, the Sun, you will need a screen of at least px across.
Rotating your screen maybe sufficient to see the Stellar values for comparison. The map was generated using Night Vision , an awesome free application by Brian Simpson. Mimosa is also a confirmed Beta Cephei variable star, but with an effective surface temperature of around 27,K, it falls into the upper limit of the instability strip, which is a position on the Hertzsprung—Russell diagram where several types of variable stars are found.
In the case of Mimosa, three distinctly different periods of pulsation, ranging between 4. Being a B0. In its present evolutionary phase, the star is emitting a strong stellar wind that is blowing off material at a rate that is about equivalent to one solar mass every one hundred million years or so.
Beta Crucis B, the secondary star in the system, is thought to be a blue main sequence dwarf star B2V , with the two A and B components having an orbital period of about 5 years, in a highly eccentric orbit that brings the stars to within 5. Becrux's location is:.
The main star in the pair is a blue-white giant star that is about 27, degrees Kelvin 48, Fahrenheit or 26, Celsius , which makes it emit most of its radiation in ultraviolet , said University of Illinois astronomer Jim Kaler.
Additionally, Becrux appears to be a particular type of variable called a Beta Cephei whose magnitudes fluctuate between 1. Becrux is the 19th brightest star in Earth's night sky. With the naked eye, Becrux's brightness appears to be 2, times greater than that of our sun, Kaler said, but luminosity is even more when looking at all types of radiation: 19, times that of the sun.
The star type tends to have temperatures of 20, to 30, K about 35, to 53, F, or 19, to 29, C. Their periods of variability vary between 0. Becrux itself is about 14 times the mass of the sun, Kaler said, and like the sun it is middle-aged; Becrux will be fusing hydrogen for about another 5. Astronomers additionally noted a rotation period of eight days, and a metal content that is a little less than the sun, at about 75 percent.
The main star Becrux may have several stellar companions, but the system will require more study before deciding this for sure, astronomers said.
The star's spectrum implies there must be a "companion" that is about 7 AU away from Becrux, but astronomers haven't been able to spot it optically yet, Kaler said.
