Which is the biggest?

The fascinating sight of the starry sky is something beautiful that the human eye can see. Looking with the naked eye in the beautiful evening hours, you can see many beautiful details in the sky. The planets that float in the sky bring an exciting experience, and many of us are thrilled with the precise orbits along which the planets move. The starry sky brings questions about the distances of the stars to us. But after a while, observers wonder – which star is the biggest of all in the sky. But after a while, observers wonder – which star is the biggest of them all in the sky. Since we only see the Milky Way stars with the naked eye, we can only talk about our galaxy.

Extremely big star

One of the biggest (if not the biggest) is the mighty UY Scuti star. The diameter of the UY Scuti is 2,376,852,800 kilometers, and is 5070 light-years away from the solar system, or about 1555 parsecs. To help you understand the UY Scuti size – we give the reduced true dimensions. If we imagine that the Earth is 20cm in size, the Sun is 22 meters, UY Scuti is big – believe it or not 40 kilometers. Although so large, UY Scuti does not see the naked eye with an apparent magnitude of 11.2. But with a small telescope, you can find this great giant in the direction of the constellation Scutum. The star is in a cloud of dust and gas, and to date no planets have been found around it. UY Scuti is classified as a pulsating star, and its brightness changes over a period of 740 days. How far is it from us? The New Horizons spacecraft travels at a speed of about 53100 kph. When flying in the direction of UY Scuti, it would reach that star in just over 103 million years.
