K2-3
K2-3, also known as EPIC 201367065, is a red dwarf star with three known planets. It is on the borderline of being a late orange dwarf/K-type star, but because of its temperature, it is classified as a red dwarf (4,000 K is typically the division line between spectral class M and K).

U1.11
U1.11 is a large quasar group located in the constellations of Leo and Virgo. It is one of the largest LQG's known, with the estimated maximum diameter of 780 Mpc (2.2 billion light-years) and contains 38 quasars. It was discovered in 2011 during the course of the Sloan Digital Sky Survey. Until the discovery of the Huge-LQG in November 2012, it was the largest known structure in the universe, beating Clowes–Campusano LQG's 20-year record as largest known structure at the time of its discovery.

WASP-104b
WASP-104b is a hot Jupiter exoplanet that orbits the star WASP-104. It is considered to be one of the darkest exoplanets discovered. WASP-104b was discovered in 2014; according to a 2018 study at Keele University, the planet's dense atmosphere of potassium and sodium absorbs more than 97% of light it receives.

K2-3 d
K2-3d, also known as EPIC 201367065 d, is a confirmed exoplanet of probable mini-Neptune
type orbiting the red dwarf star K2-3, and the outermost of three such planets discovered in the system. It is located away from Earth in the constellation of Leo. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. It was the first planet in the Kepler "Second Light" mission to receive the letter "d" designation for a planet. Its discovery was announced in January 2015.
