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.
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.
What color is TrES-2b?
An alien world blacker than coal, the darkest planet known, has been discovered in the galaxy. The world in question is a giant the size of Jupiter known as TrES-2b.
How close is TrES-2b to its star?
750.2 light years
TrES-2b/Distance to Earth
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.
What planet is the brightest?
Venus
Venus is brightest at what’s called greatest illuminated extent, or greatest brilliancy. It happens when Venus is relatively near Earth, and when telescopes show it in a crescent phase, like a tiny crescent moon.
On what planet does it rain acid?
Sulfuric-Acid Rain Venus is like Earth on (sulfuric) acid. Its atmosphere is made of dense carbon-dioxide clouds and this extremely corrosive substance, which can explode when water is added.
What color is Venus?
Venus is entirely covered with a thick carbon dioxide atmosphere and sulphuric acid clouds which give it a light yellowish appearance.
Where is TrES-2b located in the Solar System?
TrES-2b aka Coal Planet (TrES-2 or Kepler-1b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System.
Is the planet TrES-2b a gas giant?
The planet’s mass and radius indicate that it is a gas giant with a bulk composition similar to that of Jupiter. Unlike Jupiter, but similar to many planets detected around other stars, TrES-2b is located very close to its star, and belongs to the class of planets known as hot Jupiters.
How is the star Tres 2B so hot?
The clouds that surround Jupiter, for example, reflect over a third of the sunlight in their path. TrES-2b orbits its star at a distance of only three million miles. The star’s intense light heats TrES-2b to a temperature of more than 1,800° Fahrenheit – much too hot for ammonia clouds.
Why does TrES-2b reflect so little light?
Watching TrES-2b and its star, Kepler detected only the slightest such dimming and brightening, though enough to ascertain that a Jupiter-size gas giant was the cause. The light reflected by the newfound extrasolar planet, or exoplanet, changed by only about 6.5 parts per million, relative to the brightness of the host star.
