A) 66.5 B) 15 C) 23.5 Version 2 Prominent in the winter sky in northern latitudes, Gemini is a popular target for stargazers because it contains several interesting deep sky objects. It is assumed that the reason behind him joining the rebels in District 13 is for revenge. Which star is most likely to become a supernova? Scientists have identified several types of supernova. Spica is the Virgo constellations brightest star. Like other red giants, this process causes Pollux to become cooler than our Sun hence its orange color and much larger: 10 times the diameter of the Sun. Gemini Power Color: Yellow. Which stars become white dwarfs? Zeus then gave Pollux the choice between spending all his time on Olympus or giving half of his immortality to his mortal brother, so that they could alternate realms together. How to choose your telescope magnification? Pollux, and by extension Castor, are sometimes identified with Apollo and Hercules or even with the founders of Rome the brothers Romulus and Remus. Scientists think it will happen some time in the next 100,000 years. They were the sons of Leda, the queen of Sparta. That means, Pollux will throw its outer layers away creating a planetary Nebula, and the remains will collapse into a white dwarf. Are there other types of stars that go supernova? Complex calculations based on data from the Hipparcos space telescope and ground-based radio telescopes indicate it is about 724 light-years away. With an apparent magnitude of 1.14, it is the brightest star in Gemini and the 17th brightest star in the sky. Castor and Pollux (or Polydeukes) are twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. C) and A D) D and B The asteroid Ceres lies at an average distance of 4 4 million kilometers from the Sun.

In a battle, Castor supposedly died and Pollux begged Zeus to let him die and be reunited with his brother. . They also had a sister, the famous Helen of Troy. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. So if you want to learn all about which stars are most likely to supernova next, then youre in the right place. Given that, and the distance that separates the two entities, the supernova will, at the very least,be visible to us for a small stretch of time, but the rest remains to be seen. Pollux has around 1.91 solar masses, almost twice than that of the Sun and about nine times its radius. Heres how it works. Measurements conducted by the Hipparcos astrometry satellite estimate that Pollux is around 33.78 light-years / 10.36 parsecs away from the Sun but other measurements put it at 34 light-years away. supernova, plural supernovae or supernovas, any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level. Probably the best month to observe the constellation is in February this is when it is the most prominent. Mira is hotter and bluer but intrinsically fainter than the Sun.

Marina D'Arechi. When that light does arrive, the intensity of the supernova, as seen here on Earth, is somewhat a debate. The first type of supernova happens in binary star systems. Now, its only a matter of time before it explodes, giving us an incredible sight in the night and daytime skies. The exoplanet orbits Pollux at a distance of about 1.64 AU in a nearly circular orbit. The stars estimated age is 724 million years. Of course, we can't ignore Antares, a super-giant in the constellation of Scorpio. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. Sirius A (Alpha Canis Majoris) Our number one star on the list. Why Do Cross Country Runners Have Skinny Legs? When you purchase through links on our site, we may earn an affiliate commission. . Located near Lambda Geminorum, next to the border with Canis Minor, the Medusa Nebula is a large old planetary nebula once believed to be a supernova remnant. They are roughly one-tenth the mass and diameter of the Sun. [12] The abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is uncertain, with estimates ranging from 85% to 155% of the Sun's abundance. The star has become a red giant. 1.93), Alhena (Gamma Gem, mag. Scientists have studied a binary star system for years and claim it will explode. Its also a likely candidate for the next star to go supernova. Therefore, the science community is constantly trying and hoping to predict which nearby star will explode next. Which process produces the largest amount of energy given off by stars? 5 How bright will Betelgeuse be when it goes supernova? Constellation Puppis second brightest star is only 1,100 light-years from Earth. 3.35), Wasat (Delta Gem, mag 3.53), and Kappa Geminorum (mag.

Betelgeuse, which is located approximately 640 light-years from Earth in the constellation Orion -- is one of the biggest and brightest stars in our galactic neighborhood. Prominent examples of stars in this mass range include Antares, Spica, [1] Gamma Velorum, [2] Mu Cephei, and . Both stars are orange giants (K0III), but Arcturus appears considerably brighter (mag. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. It has almost 9 times the suns radius 8.8 solar radii, almost eighteen times its diameter and around 2 times its mass 1.91 solar masses. According to a new study, a star discovered 75 light-years away is no warmer than a freshly brewed cup of coffee. So just how long will we have to wait for the next show? The plane was planned to execute test maneuvers that year and to get to a top re-entry speed of Mach 1.2. The prefix "super-" was added to distinguish supernovae from ordinary novae, which are far less luminous. Our Sun currently approaching the midway point of its life can expect to live for 10 billion years, but Betelgeuse will only live for roughly a thousandth of that time. Supernova can produce elements like titanium, iron, cobalt and nickel. Type II supernova progenitors include stars with at least 10 solar masses that are in the final stages of their evolution.
