TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System. The planet was identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it.

2024年12月7日 · TrES-2 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.49 Jupiters, it takes 2.5 days to complete one orbit of its star, and is 0.03568 AU from its star. Its discovery was announced in 2006.

2011年9月26日 · TrES-2b, which was discovered in 2006, is one of roughly 150 hot Jupiter planets known to exist outside our solar system. Astronomers are working to better understand the sometimes mysterious properties of these "dark" planets, from their mass to their orbital patterns to their atmospheric makeup.

2011年8月12日 · Orbiting only about three million miles out from its star, the Jupiter-size gas giant planet, dubbed TrES-2b, is heated to 1,800 degrees Fahrenheit (980 degrees Celsius). Yet the apparently...

2011年8月12日 · Astronomers have discovered the darkest known exoplanet — a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than 1 percent of the sunlight falling on it, making it blacker than coal or any planet or …

TrES-2b is an exoplanet that is 750 light-years away. This planet is the darkest known exoplanet, reflecting less than 1% of all light that comes across it. It is now also believed to be orbiting a binary star system(a system where two stars orbit each other).

2011年8月11日 · TrES-2b, shown here in an artist's conception, is darker than the blackest coal. This Jupiter-sized world reflects less than one percent of the light that falls on it, making it blacker than any planet or moon in our solar system.

2011年8月18日 · TrES-2b is mostly hydrogen as well, but since it’s only 3 million miles from its star — more than 160 times closer than Jupiter is to the sun — TrES-2b simmers at a toasty 1,800 degrees.
