TYC 8998-760-1 is a young star, about 17 Ma old, located 310 light years away in the constellation of Musca, with a mass 1.00±0.02 times the Sun.
TYC 8998-760-1 b and a companion planet orbit a very young, Sun-like star some 300 light-years away. The star, about the same size as our Sun, is only about 17 million years old – a baby among stars. That means the star's planets formed only recently, and are still so hot that they give off a powerful glow detectable by ground-based telescopes.
Capturing pixels of light directly from exoplanets is extremely difficult because the light from these worlds is overwhelmed by the glare from their stars. TYC 8998-760-1 b joins the thin ranks of such detections. It might be a brown dwarf – a kind of "failed star" – that is considered neither a star nor a planet, but somewhere in between.
Brown dwarfs are mysterious worlds, with many unanswered questions about their properties and appearance. They're too massive to be planets, but not quite massive enough to be stars. TYC 8998-760-1 b is immense, about 14 times the mass, or heft, of our own planet Jupiter, and likely three times as big around. The estimated temperature at its surface is about 2,600 degrees Fahrenheit (1,400 degrees Celsius). This object's extreme girth is unusual for brown dwarfs, and could indicate that its youthful atmosphere is highly inflated. Another possibility, which can't yet be ruled out, is that it's really two objects orbiting each other, these in turn orbiting the star.
In July 2020 a companion planet, TYC 8998-760-1 c, was discovered and the two were directly imaged together.
The SPHERE instrument on ESO’s Very Large Telescope (VLT) has captured the first ever image of a young, Sun-like star accompanied by two giant exoplanets, located about 300 light-years away from Earth. This video takes us on a journey to this system.
In another exoplanetary first, the European Southern Observatory's Very Large Telescope (VLT) in Chile's Atacama Desert has captured an image of two worlds orbiting a younger version of the Sun. The system, called TYC 8998-760-1, is located roughly 300 light-years away in the southern constellation Musca. And although it hides two gas giants orbiting a Sun-like star, we don’t have anything quite like these worlds in our own solar system.
The inner planet lies about 160 astronomical units from its host star (where one astronomical unit, or AU, is the average Earth-Sun distance) and is some 14 times the mass of Jupiter. With that amount of heft, the gas giant skirts the border between planet and brown dwarf, which is a type of almost-star. The more distant planet is located about 320 AU from its star and weighs in at about six Jupiter masses.
The system’s star, meanwhile, has about the same mass as our own Sun (give or take a few percent due to uncertainties). However, it’s only 17 million years old — which makes our roughly 4.5-billion-year-old Sun about 265 times older.
The direct imaging of two or more exoplanets around the same star is even more rare; only two such systems have been directly observed so far, both around stars markedly different from our Sun. The new ESO’s VLT image is the first direct image of more than one exoplanet around a Sun-like star. ESO’s VLT was also the first telescope to directly image an exoplanet, back in 2004, when it captured a speck of light around a brown dwarf, a type of ‘failed’ star.
The two gas giants orbit their host star at distances of 160 and about 320 times the Earth-Sun distance. This places these planets much further away from their star than Jupiter or Saturn, also two gas giants, are from the Sun; they lie at only 5 and 10 times the Earth-Sun distance, respectively. The team also found the two exoplanets are much heavier than those in our Solar System, the inner planet having 14 times Jupiter’s mass and the outer one six times.
