Kepler-415 b has a radius of 1.21 times that of Earth. Its mass is 120 times that of Earth.

Is Kepler-415 b in the Habitable Zone?

The position of Kepler-415 b relative to the habitable zone of Kepler-415 cannot be precisely determined from the available orbital data.

Orbit and Year Length

A year on Kepler-415 b — one full orbit around Kepler-415 — lasts 4.18 Earth days, shorter than Mercury's 88-day year.

How Was Kepler-415 b Discovered?

Kepler-415 b was discovered in 2014 using the transit timing variations method, with observations from Kepler.

Transit timing variations reveal a planet through its gravitational tug on a sibling planet, which makes that sibling's transits arrive slightly early or late. The pattern of these deviations betrays the hidden planet's mass and orbit.

How Far Away Is Kepler-415 b?

Kepler-415 b is 1,730.2 light-years (530.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,730 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 30,451,520 years to make the journey.

Earth Similarity Index

The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. Kepler-415 b scores 0.31, ranking #1,230 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-415 b

Is Kepler-415 b habitable?

Kepler-415 b is not known to orbit within the habitable zone of Kepler-415, and as a terrestrial planet it is an unlikely candidate for life as we know it.

How far away is Kepler-415 b?

Kepler-415 b is about 1,730 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 30,451,520 years to get there.

How big is Kepler-415 b compared to Earth?

Kepler-415 b has 1.21 times the radius of Earth and about 120 times its mass.

How long is a year on Kepler-415 b?

One orbit around Kepler-415 takes 4.2 Earth days — short enough that 87 of its years would fit into one Earth year.
