Kepler-87b is a confirmed gas giant exoplanet orbiting the star Kepler-87.

Here are some key facts about it:

Type: Gas giant

Mass: 1.02 times the mass of Jupiter. This is equivalent to approximately 324 Earth masses.

Radius: About 13.5 Earth radii.

Orbital Period: Takes 114.7 days to complete one orbit around its star.

Distance from its star: 0.481 Astronomical Units (AU), which is closer than Mercury is to our sun.

Discovery: Its discovery was announced in 2013.

Host star: Kepler-87, a G-type star.

Density: Relatively low density, about 73% of the density of liquid water.

Not habitable: It's considered a gas giant and not habitable.

    i wonder how planets are really formed. how can a big blob of methane gain gravitational force and grow bigger than earth.

      Hello, planets start as dust in a disk around a young star. Dust clumps form bigger rocks. If big enough, gravity pulls in gas, making gas giants like Jupiter. A core of rock or ice usually forms first, then grabs the gas.
