Every evening, when we look up at the sky, we can admire the beauty of the many visible stars. What if we told you that we actually cannot see the biggest star in the sky?
What if we told you that we actually cannot see the biggest star in the sky? Below is an observation in the infrared spectrum R Dorados, Variable star In the constellation Dorado (Swordfish), located in the far south of the sky. Its rotation period is about 338 days, which changes its magnitude from about 4.8 maximum (when visible with the naked eye) to 6.6 minimum (when a small telescope is required). It is located about 200 light-years away.
Details by R Dorados
Its physical diameter is 370 ± 50 times the diameter of the Sun, or more than 250 million kilometers! If R Doradus were at the center of the solar system, its surface would reach beyond the orbit of Mars! Although they are known Even the biggest stars – Like Betelgeuse – none of them appear large in the sky because they are all located at greater distances. The dimensions shown are very large The emergence of R Doradus is due to the combination of its relative proximity and large physical size.
In its own small way, Passione Astronomia helps you understand how the universe works. And the universe works better if the people who are part of it are well informed: if they have read nonsense, lies, and poison, it will end as it did. Things are not going well right now. That's why it's important for someone to explain things well. Passionate Astronomy is doing its best. Participate!
