This is an artist’s impression of a hot Jupiter orbiting close to a star.

This is an artist’s illustration a massive planet orbiting a cool, young star. In the case of the newly discovered system, the planet is 10 times more massive than Jupiter, and the orbit of the planet is nearly 600 times that of Earth around the sun.

Welcome to the KELT-9 system. The host star is a hot, rapidly rotating A-type star that is about 2.5 times more massive and almost twice as hot as our sun. The hot star blasts its nearby planet KELT-9b with massive amounts of radiation, leading to a daylight temperature of 7800 degrees Fahrenheit, hotter that most stars and only 2000 degrees cooler than the sun.

This is an artist’s rendering of the Proxima Centauri planetary system. The newly discovered super-Earth exoplanet Proxima c, on the right, has an orbit of about 5.2 Earth years around its host star. The system also comprises the smaller Proxima b, on the left, discovered in 2016. Illustration by Lorenzo Santinelli.

A super-telescope made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex exoplanetary atmosphere with clouds of iron and silicates swirling in a planet-wide storm. The technique presents unique possibilities for characterizing many of the exoplanets known today.

An artist’s illustration of what the super-Earth found around the orange-hued star HD 26965 (also known as 40 Eridani A) might look like.

The TRAPPIST-1 star, an ultra-cool dwarf, has seven Earth-size planets orbiting it.

For the first time, eight planets have been found orbiting another star, tying with our solar system for the most known planets around a single star. The Kepler-90 system is in the constellation Draco, more than 2,500 light-years from Earth.

This artist’s illustration shows exoplanet Ross 128 b, with its red dwarf host star in the background. The planet is only 11 light-years from our solar system. It is now the second-closest temperate planet to be detected, after Proxima b.

WASP-121b, 880 light-years away, is considered a hot Jupiter-like planet. It has a greater mass and radius than Jupiter, making it “puffier.” If WASP-121b were any closer to its host star, it would be ripped apart by the star’s gravity.

This artist’s concept shows OGLE-2016-BLG-1195Lb, a planet orbiting an incredibly faint star 13,000 light-years away from us. It is an “iceball” planet with temperatures reaching minus-400 degrees Fahrenheit.

LHS 1140b is located in the liquid water habitable zone surrounding its host star, a small, faint red star named LHS 1140. The planet weighs about 6.6 times the mass of Earth and is shown passing in front of LHS 1140. Depicted in blue is the atmosphere the planet may have retained.

An artist’s concept image of the surface of the exoplanet TRAPPIST-1f. Of the seven exoplanets discovered orbiting the ultracool dwarf star TRAPPIST-1, this one may be the most suitable for life. It is similar in size to Earth, is a little cooler than Earth’s temperature and is in the habitable zone of the star, meaning liquid water (and even oceans) could be on the surface. The proximity of the star gives the sky a salmon hue, and the other planets are so close that they appear in the sky, much like our own moon.
