Only a few planets, the entire moon, and the International Space Station shine brighter than this star.

Sirius is twice as massive, 21 times larger, and shines 250 times brighter than our sun.
What is the brightest thing in the universe?
Quasars are extremely bright, despite the fact that they appear faint from Earth. They are the most luminous things in the known universe, and 3C 273 is the brightest quasar in the sky. Virgo’s 3C 273 is a spectacular sight, with an apparent magnitude of 16.8 (Virgo).
Which planet has the longest year?
Neptune’s orbital period is the longest of any planet in the Solar System, at 165 years. As a result, a year on Neptune lasts roughly the same length as 60,182 Earth days (164.8 years).
Which is the biggest star?
The Pistol Star is the world’s biggest known star (in terms of mass and brightness) with a radius of some 33,000 miles. It is thought to be 100 times as massive as our Sun and 10,000,000 times as bright! In 1990, a star called the Pistol Star was discovered to lie at the heart of the Milky Way. The Pistol Star is believed to be 30,000 times as bright as our Sun.

Is Venus brighter than Sirius?
Sirius, the brightest star in the sky, has a magnitude of -1.4. This indicates that even at its maximum brightness, Venus is 17 times brighter than Sirius.
Why do stars twinkle?
When light from a star passes through our atmosphere, it is bounced and jostled across the many layers, bending the light before it reaches your eyes. The flexing of the light as the hot and cold air layers continue to move causes the star’s appearance to fluctuate or twinkle.
What is the darkest thing in the universe?
Vantablack is a dark material produced by Surrey NanoSystems in the United Kingdom, which absorbs up to 99.965% of visible light (at 663 nm if the light is perpendicular to the substance).
What is the fastest thing in the universe?
Lasers shoot laser beams at nearly 670 million miles per hour, making them the fastest things in existence.
What is the most dangerous thing in the universe?
Supermassive black holes are unusual. The heaviest black hole discovered thus far weighs 20 times the mass of the Sun, or twice the size of our solar system. In contrast to the outer planets in our solar system, which take 250 years to orbit once, this much larger object spins every three months.
