The size of UY Scuti compared to Earth's orbit and the Sun (barely visible) UY Scuti is a dust-enshrouded bright red supergiant [16] and is classified as a semiregular variable with an approximate pulsation period of 740 days.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [90] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [96] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [97]

Stephenson 2 DFK 1, also known as RSGC2-01 [a] or St2-18, is a red supergiant (RSG) or possible extreme red hypergiant [2] (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a ...
A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds.The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.
VY Canis Majoris (abbreviated to VY CMa) is an extreme oxygen-rich red hypergiant or red supergiant (O-rich RHG or RSG) and pulsating variable star 1.2 kiloparsecs (3,900 light-years) from the Solar System in the slightly southern constellation of Canis Major.
EBLM J0555-57 is a triple star system approximately 670 light-years from Earth. The system's discovery was released on July 12, 2017. EBLM J0555-57Ab, the smallest star in the system, orbits its primary star with a period of 7.8 days, and currently is the smallest known star with a mass sufficient to enable the fusion of hydrogen in its core.
Beta Scuti is the second brightest at magnitude 4.22, followed by Delta Scuti at magnitude 4.72. It is also known as 6 Aquilae. [7] Beta Scuti is a binary system, [8] [9] with the primary with a spectral type similar to the Sun, although it is 1,270 times brighter. Delta Scuti is a bluish white giant star, which is now coming at the direction ...
