Is HD 189733b a gas planet?
HD 189733b is believed to be a “gas giant” planet similar in size to Jupiter and, as such, is thought to be a hostile environment for life. Its close orbit around its sun is not conducive to living organisms, which are highly unlikely to survive the daytime temperatures of more than 1,000C.

What is the exoplanet made out of?
Exoplanets are made up of elements similar to that of the planets in our solar system, but their mixes of those elements may differ. Some planets may be dominated by water or ice, while others are dominated by iron or carbon.
How old is HD 189733b?
600 million years old
Stellar system The star is between 89 and 102 percent as enriched in iron as the Sun, making the star more than 600 million years old. The star has starspots which affect its luminosity by 1.5 percent in visible light.

How much is a diamond exoplanet worth?
But the most fabulous potential space fortune may be “the diamond planet,” the more technical name of which is 55 Cancri e. This exoplanet is twice the size of earth and may be made up of one-third diamonds. That diamond cache could be worth $26 nonillion (that’s 30 zeros), according to “The Filthy Rich Guide.”
How big is the planet HD 189733 b?
Howling winds send the storming glass sideways at 5,400 mph (2km/s), whipping all in a sickening spiral. It’s death by a million cuts on this slasher planet! HD 189733 b is a gas giant exoplanet that orbits a K-type star. Its mass is 1.13 Jupiters, it takes 2.2 days to complete one orbit of its star, and is 0.0313 AU from its star.
What kind of atmosphere does HD 189733b have?
In July 2014, NASA announced finding very dry atmospheres on three exoplanets (HD 189733b, HD 209458b, WASP-12b) orbiting Sun-like stars. The infrared spectrum of HD 189733 b. A global temperature map of HD 189733 b. The planet’s blue color was revealed using polarimetry.
What makes HD189733b different from other planets?
The closeness of HD189733b is what really puzzles scientists. The conventional theories of planetary formation state that rocky planets orbit closer to their stars while the gaseous giants are located farther out. HD189733b defies this theory.
How much is the atmosphere fleeing the planet HD189733b?
HD189733b’s atmosphere is fleeing the planet at a rate of 220 million pounds (100 million kilograms) to 1.3 billion pounds (600 million kg) a second, a new study estimated.
