    TOI-1338 b, also nicknamed Wolftopia, is a gas giant circumbinary exoplanet in the constellation Pictor orbiting around the binary star system TOI-1338, first identified by then-17-year-old Wolf Cukier. It's the first circumbinary planet discovered by the Transiting Exoplanet Survey Satellite (TESS). [4] It was found on 31 July 2019, and announced on 6 January 2020. [5] [6] In terms of diameter, it's around 6.9 times the diameter of Earth. [7] It orbits 1318 light years away from Earth [3] , which calculates to 12,469,242,762,860,496 kilometers, or 7,748,028,241,855,326 miles.

    Wolf's brother, Ben Cukier, suggested the name Wolftopia, as a combination of the words wolf and city, although Wolf said he didn't particularly like the name. [8]

    Discovery

    Wolf Cukier, a 17-year-old attending Scarsdale High School in New York at the time, joined the Goddard Space Flight Center in 2019 to work as a summer intern, later to find TOI-1338 b on his third day of interning. [9] He studied data that was flagged as an eclipsing binary provided by volunteers of the Planet Hunters citizen science project. [10] He and 6 of the volunteers are co-authors of the publication regarding TOI-1338 b. [1] Cukier then attended Princeton University, and graduated in 2024.

    The discovery of TOI-1338 b was announced on 6 January at the 235th American Astronomical Society meeting in Honolulu, Hawaii. [11] In February 2021, a petition was launched calling for TOI-1338 b to be renamed SOPHIE in honor of the recently deceased British musician Sophie. [12] [13] Both Charlie XCX and Caroline Polachek [12] supported the petition, but it ended up unsuccessful. However, the International Astronomical Union announced that that the minor planet 1980 RE1 would permanently get the name Sophiexeon (after Sophie's full name).

    Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on 18 April 2018, atop a Falcon 9 launch vehicle and was placed into a highly elliptical 13.70-day orbit around the Earth. The first light image from TESS was taken on 7 August 2018, and released publicly on 17 September 2018.

    Planet Hunters is a citizen science project to find exoplanets using human eyes. It does this by having users analyze data from the NASA Kepler space telescope and the NASA Transiting Exoplanet Survey Satellite. It was launched by a team led by Debra Fischer at Yale University, as part of the Zooniverse project.

    TOI-677 b is a confirmed "warm" super-Jupiter exoplanet orbiting TOI-677, its host star, in the Ophiuchus constellation, about 466 ly (143 pc) away from Earth. The planet was discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Discovery of the exoplanet was announced on 13 November 2019.

    TOI-700 is a red dwarf 101.4 light-years away from Earth located in the Dorado constellation that hosts TOI-700 d, the first Earth-sized exoplanet in the habitable zone discovered by the Transiting Exoplanet Survey Satellite (TESS).

    TOI-700 d is a near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf TOI-700, the outermost planet within the system. It is located roughly 101.4 light-years (31.1 pc) away from Earth in the constellation of Dorado. The exoplanet is the first Earth-sized exoplanet in the habitable zone discovered by the Transiting Exoplanet Survey Satellite (TESS).

    TOI-1338 is a binary star system located in the constellation Pictor, about 1,320 light-years from Earth.

    TOI-628 b is an exoplanet whose mass is 6.33 times that of Jupiter. It has an orbital period of 3.4 days and was discovered by TESS in January 2021. The planet is classified as hot Jupiter, having a equilibrium temperature of 1,586 K (1,313 °C), and a radius 6% larger than that of Jupiter. It is located 583 light years away from Earth.

    HD 63433 c is a mini-Neptune exoplanet orbiting the Sun-like star HD 63433. It is the outermost planet in its planetary system, being located 0.1448 astronomical units (21,660,000 km) from its star, and completing one orbit every 21 days. Despite being the outermost planet in the system, it is still located close to its star, meaning that its temperature is hot, being estimated between 267 and 406 °C. HD 63433 c is about 2.7 times larger than Earth and 15.5 times more massive, but still smaller and less massive than Neptune. In 2022, a study showed that its atmosphere, made up of hydrogen, is being evaporated by the strong radiation from its star, causing it to slowly turn into a super-Earth planet.
