How old is the UY Scuti star?
The age of UY Scuti has not been calculated but it could be as young as few million years or as old as a few billion. In other words, we are uncertain to the age of the star. No ones lived as long as a star so no one knows for certain a stars age, its only a best guess estimation.
Where in the sky is UY Scuti?
UY Scuti lies two degrees north of the white magnitude 4.67 star Gamma Scuti, in the region of the sky just northeast of the famous Eagle Nebula (Messier 16). The star can be observed in a 4-inch or larger telescope in good conditions.
Can I see UY Scuti from Earth?
UY Scuti is located in or galaxy the Milky Way, at about 5.219 light-years away from Earth. UY Scuti changes its brightness but it can be viewed from Earth as it is a pulsating star.
When was Hipparchus born?
190 BCHipparchus / Date of birth
Hipparchus was born in Nicaea, Bithynia (now Iznik, Turkey), circa 190 B.C. He spent much of his time in Rhodes, Greece. Very little is known about his life, but he was one of the greatest astronomers and mathematicians of antiquity.
What did Hipparchus do as a kid?
Born in Nicaea, Bithynia (now Iznik, Turkey), Hipparchus lived in the 2nd century bc. As a young man he compiled records of local weather patterns throughout the year.
Where is Hipparchus from?
NicaeaHipparchus / Place of birth
Hipparchus, also spelled Hipparchos, (born, Nicaea, Bithynia [now Iznik, Turkey]—died after 127 bce, Rhodes?), Greek astronomer and mathematician who made fundamental contributions to the advancement of astronomy as a mathematical science and to the foundations of trigonometry.
How did Hipparchus discover a Nova?
Hipparchus discovered the precession of the equinoxes and observed the appearance of a new star – a nova. He suspected stars might move slowly with respect to one another over great lengths of time; he hoped people living in the future could verify this.
Where was Hipparchus born?
How big is black hole in Milky Way?
The size of a black hole is defined by its event horizon — a distance from the center of the black hole within which nothing can escape. Scientists had previously been able to calculate that Sagittarius A* is 16 million miles (26 million kilometers) in diameter.
Who is the biggest sun?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.
When did Hipparchus live?
190 BC – 120 BCHipparchus / Years of Living
Why is Hipparchus famous?
Solar and lunar theory. Hipparchus’s most important astronomical work concerned the orbits of the Sun and Moon, a determination of their sizes and distances from Earth, and the study of eclipses.

Can a black hole reach Earth?
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
What is the nine planets?
The Nine Planets is a multimedia website by Bill Arnett containing information about the Solar System. It was one of the first examples of a multimedia website when it first appeared on the World Wide Web in 1994 and, as was common for high traffic websites at the time, it was widely mirrored.
What is the Planet Nine hypothesis?
The Planet Nine hypothesis includes a set of predictions about the mass and orbit of the planet. An alternative theory predicts a planet with different orbital parameters.
What is Planet X or Planet Nine?
Planet Nine, sometimes referred to as Planet X, is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.
What is the orbital period of Planet Nine?
^ As of 2021 the semi-major axis of Planet Nine is estimated by Brown & Batygin to be between 360 to 620 AU; this implies that the planet has an orbital period between around 6,800 (3601.5) to 15,400 (6201.5) years. ^ A range of semi-major axes extending from 400 AU to 1000 AU produce the observed clustering in simulations.
