Is J1407b a real planet?

Is J1407b a real planet?

J1407b is an extrasolar planet located about 420 light-years from Earth in the constellation of Centaurus. The planet was discovered in 2012 by the University of Rochester, located in New York.

Can we see J1407b from Earth?

From Earth, the orbit of J1407b is seen almost edge on, and the rings block the light of the star.

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 color is J1407b?

J1407b is the first exoplanet or brown dwarf discovered with a ring system by the transit method.

How does J1407b keep its rings?

Having retrograde rotation means that the particles of the ring system are never too close to the star for too long, and thus can stay together.

What are J1407b rings made of?

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.

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 does J1407b have so many rings?

Make no mistake, J1407b is the true Lord of the Rings. Scientist could infer the presence of a large ring system because of the way it blocked light from the planet’s host star. Here is a video released by the discovery team showing the drop in the star’s brightness during what can be called a ring-eclipse.

What is J1407b rings made of?

What happens if J1407b replaced Saturn?

If we could replace Saturn’s rings with the rings around J1407b, they would be easily visible at night and be many times larger than the full moon.

What if Earth had 2 moons?

The consequences of a second moon orbiting the Earth depend on how massive that moon is and how far from the Earth it orbits. The most obvious effect would be that the ocean tides would be altered. Tides could be either smaller or higher and there could be more than two high tides per day.

Is J1407b a planet with rings?

Artist’s conception of the extrasolar ring system circling the young giant planet or brown dwarf J1407b. The rings are shown eclipsing the young sun-like star J1407, as they would have appeared in early 2007.

When was J1407b discovered?

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.

Does J1407 have satellites?

“In the case of J1407, we see the rings blocking as much as 95 percent of the light of this young Sun-like star for days, so there is a lot of material there that could then form satellites.” In the data the astronomers found at least one clean gap in the ring structure, which is more clearly defined in the new model.

Is J1407’s ring system bigger than Saturn’s?

Astronomer Eric Mamajek at the University of Rochester and his co-author from the Leiden Observatory, The Netherlands, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.
