Discussion Overview

The discussion revolves around the discovery of the exoplanet Kepler-10c, referred to as a "mega-Earth," which is significantly heavier than Earth. Participants explore its characteristics, potential classification, and implications regarding planetary formation, particularly in relation to gas giants.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants express astonishment at the size of Kepler-10c, referring to it as a "monster."
  • One participant suggests that Kepler-10c's mass is comparable to the rocky cores of gas giants, proposing it might be a failed gas giant formed after gas was lost during the T-Tauri stage of development.

Areas of Agreement / Disagreement

Participants generally express excitement about the discovery, but there is no consensus on the implications of its mass or its classification as a failed gas giant.

Contextual Notes

The discussion includes speculative ideas about planetary formation and classification, with assumptions about the conditions during the T-Tauri stage remaining unresolved.

'Godzilla of Earths': Alien Planet 17 Times Heavier Than Our World Discovered

BOSTON — Scientists have just discovered the "Godzilla of Earths" — a new type of huge and rocky alien world about 560 light-years from Earth.

Dubbed a "mega-Earth," the exoplanet Kepler-10c weighs 17 times as much as Earth and it circles a sunlike star in the constellation Draco. The mega-Earth is rocky and also bigger than "super-Earths," which are a class of planets that are slightly bigger than Earth.

Whew... it's quite a monster, isn't it?
 
yeesh that is a big one thanks for posting it
 
So, it is the same order of magnitude as the rocky core thought to lie at the heart of gas giants. Might this be a failed gas giant whose core formed after gas was swept from the system at the T-Tauri stage of development?
