TrES-2b 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 is the most dangerous planet?
0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
What is the strangest exoplanet?
Kepler-78b – A Lava Planet
Kepler-78b is similar to our planet Earth. This exoplanet is in the Cygnus constellation. The strangest thing about it, though, is how close it is to its host star: it is only 550,000 miles (885,139 kilometers) away.

What is the safest planet to live?
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
- Its soil contains water to extract.
- It isn’t too cold or too hot.
- There is enough sunlight to use solar panels.
- Gravity on Mars is 38% that of our Earth’s, which is believed by many to be sufficient for the human body to adapt to.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What is the rarest planet?
Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What is the oldest planet?
At 12.7 billion years old, planet Psr B1620-26 B is almost three times the age of Earth, which formed some 4.5 billion years ago. This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What’s the coldest thing known to man?
The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. Outflows of gas, streaming out from the central dying star, reach temperatures below -270 degrees Celsius.
What is the biggest star?

How many Super Earths are there?
Since 2009, the Kepler Space Telescope has discovered about 4,000 exoplanets. 30% of them are super-earths. And a few percent of those super-earths orbit within their host star’s habitable zone: That’s a Goldilocks zone where the planet’s surface is just the right temperature for liquid water.
What planet rotates the fastest?
Good luck getting any sleep on Jupiter! This humongous gas giant rotates faster than any other planet in the Solar System, completing a day in less than 10 hours!
What is the biggest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
