IC 1011
IC 1011 is a galaxy described as a compact elliptical galaxy[3] with apparent magnitude of 14.7,[4] and with a redshift of z=0.02564 (SIMBAD)[1] or 0.025703 (NASA),[4] yielding a distance of 100 to 120 Megaparsecs.[4] Its light has taken 349.5 million years to travel to Earth. IC 1011's calculated age is approximately 12.95 billion years.[4] The IC designation comes from the Index Catalogue.
VY Canis Majoris
VY Canis Majoris (VY CMa) is the largest known star by radius and also one of the most luminous. It is a red hypergiant in the constellation Canis Major. It is 1800–2200 solar radii (8.2–10.2 astronomical units) in radius, about 3.0 billion km (1.864 billion mi) in diameter, and about 1.5 kiloparsecs (4,900 light-years) distant from Earth. VY CMa is a single star categorized as a semiregular variable and has an estimated period of 2,000 days. It has an average density of 5 to 10 mg/m3.
If placed at the center of the Solar System, VY Canis Majoris's surface would extend beyond the orbit of Jupiter although there is still considerable variation in estimates of the radius, with some making it larger than the orbit of Saturn.
