Is TrES-2b bigger than Jupiter?
Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on it, making it blacker than coal or any planet or moon in our solar system. Astronomers have discovered the darkest known exoplanet — a distant, Jupiter-sized gas giant known as TrES-2b.
Is TrES-2b a real planet?
TrES-2b (TrES-2 or Kepler-1b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System. The planet has been identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it.
Why is planet TrES-2b so dark?
Explanation: Why is this planet so dark? Planet TrES-2b reflects back less than one percent of the light it receives, making it darker than any known planet or moon, darker even than coal.
How close is TrES-2b to its star?
750.2 light years
TrES-2b/Distance to Earth
The world in question is a giant the size of Jupiter known as TrES-2b. NASA’s Kepler spacecraft detected it lurking around the yellow sun-like star GSC 03549-02811 some 750 light years away in the direction of the constellation Draco.
Is TrES 2b hot or cold?
TrES-2b orbits its star at a distance of only 3 million miles. The star’s intense light heats TrES-2b to a temperature of more than 1,800 degrees Fahrenheit — much too hot for ammonia clouds.
Is there a GREY planet?
Mercury: Mercury is difficult planet to get good images of, and for obvious reasons. And what we have seen is a dark gray, rocky planet.
Is TrES-2b hot or cold?
What planet is the brightest?
Venus
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.
How long is a day on TrES 2b?
The planet known as TrES-2b is an interesting and useful place. Just over Jupiter mass, it orbits a solar mass star some 717 light years from Earth, a ‘hot Jupiter’ in a tight 2.47-day orbit.
Is there gold in the moon?
Golden Opportunity on the Moon The moon isn’t so barren after all. A 2009 NASA mission—in which a rocket slammed into the moon and a second spacecraft studied the blast—revealed that the lunar surface contains an array of compounds, including gold, silver, and mercury, according to PBS.
What if the earth was cut in half?
As the Earth is methodically sliced in half, its mantle and core would be exposed to the vacuum of space, causing massive earthquakes that would be felt everywhere on the planet. At this stage, almost all of the planet’s human inhabitants — 7.5 billion people — would be without electricity.
What type of planet is tres2b?
TrES-2b ( TrES-2 or Kepler-1b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System. The planet has been identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it. The planet’s mass and radius indicate that it is a gas giant…
Is TrES-2b the darkest exoplanet?
The first important result from the Kepler Mission about TrES-2b is an extremely low geometric albedo measured in 2011, making it the darkest known exoplanet. If the entire day–night contrast were due to geometric albedo, it would be 2.53%, but modeling suggests that much of this is dayside emission and the true albedo is much lower.
What does TrES-2 stand for?
TrES-2b (TrES-2 or Kepler-1b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System.
How was TrES-2b discovered?
TrES-2b was discovered on August 21, 2006 by Trans-Atlantic Exoplanet Survey (TrES) by detecting the transit of the planet across its parent star using Sleuth (Palomar Observatory, California) and PSST (Lowell Observatory, Arizona), part of the TrES network of 10-cm telescopes.
