How big is J1407b vs Earth?
How big is J1407b vs Earth?
Meet J1407b – an exoplanet 20 times more massive than Saturn. The rings of this Super Saturn span 180 million kilometers wide. That’s larger than the Earth-Sun distance of 150 million kilometers and 200 times bigger than Saturn’s rings!
How far away is J1407b from Earth?
433.8 light yearsJ1407b / Distance to Earth
Is J1407b bigger than Jupiter?
J1407b itself is estimated to contain 10-40 times the mass of Jupiter – technically, it might even be a brown dwarf. Further observations will be required to observe another transit of J1407b and obtain more data on its rings and other physical characteristics as its orbit is about ten Earth-years long.
What is the radius of J1407b?
The J1407b ring system has an outer radius of approximately 90 million km (about 640 times the extent of Saturn’s rings). Cleared gaps in the rings indicate satellites (“exomoons”) have formed accreted from denser rings.
Can you see J1407b from Earth?
The planet J1407b orbits around the star, called J1407. The rings orbit around the planet, and both the planet and the rings move around the star. From Earth, the orbit of J1407b is seen almost edge on, and the rings block the light of the star. Credit: Kenworthy, Leiden.
What universe is J1407b in?
J1407b is an extrasolar planet located 433.8 light-years from Earth in the constellation of Centaurus.
What is special about J1407b?
Astronomers say they have found the first ringed planet beyond our solar system, a super world with a girdle of halos 200 times bigger than Saturn’s. Called J1407b, the giant has a disk of 30-odd rings which is so vast that had it been around Saturn, it would have dominated our night sky.
Where is J1407b located?
J1407b is an extrasolar planet located 433.8 light-years from Earth in the constellation of Centaurus. The planet was discovered in 2012 by the University of Rochester, located in New York.
What is interesting about J1407b?
The exoplanet, called J1407b, could even harbor at least one Earth or Mars-sized moon, judging by a large gap in the rings, scientists have found. This discovery marks the first time researchers have found this kind of ring system outside of the solar system. Exoplanets reveal themselves in their host star’s light.
What is the weather like on J1407b?
The rings begin at a distance of about 30 million kilometres from the planet and stretch out to a distance of 90 million kilometres. And they are probably made of dust, as planet J1407b is too hot – about 1,000 to 2,000 degrees Celsius – to support ice rings like those orbiting Saturn.
What solar system is J1407b?
Artist’s conception of the extrasolar ring system circling the young giant planet or brown dwarf J1407b.
Is J1407b real?
The planet was discovered in 2012 by the University of Rochester, located in New York. J1407b is widely known for the massive size of its rings, which are approximately 640 times the extent of the rings found on Saturn. The planet itself is regarded as the first possible exoplanet, or brown dwarf with a ring system.
