Confirmation of Existence

Astrophysicist Stephen Kane from the University of California - Riverside was initially taken aback by the findings and meticulously verified his calculations to confirm the existence of this remarkable planet.

Observations from TESS

The discovery was made while studying the star system HD 104067, located approximately 66 light years away from Earth, using data gathered by NASA's Transiting Exoplanet Survey Satellite (TESS), launched in 2018.

Characteristics of the  New Planet

This newly identified planet, named TOI-6713.01, shares similarities with Earth in terms of its rocky composition but exceeds Earth's size by more than 30%. However, its most striking resemblance is to Io, Jupiter's volcanic moon.

Comparison to Io

Kane likens the new planet to "Io on steroids," highlighting its volcanic activity and molten lava surface. Gravitational forces, similar to those affecting Io, drive the volcanic eruptions on TOI-6713.01.

Tidal Energy Dynamics

The eccentric orbit of TOI-6713.01, influenced by outer planets in its system, generates tidal energy, heating the planet's surface akin to a racquetball constantly struck with paddles.

Implications for Further Research

Researchers are eager to determine the planet's mass and density to gain insights into the availability of volcanic materials. This research will shed light on the dynamics of tidal energy and volcanic activity on extraterrestrial bodies.
