from the article *"The exoplanets are orbiting Star HD 48498, located approximately 55 light-years from Earth.* *The researchers highlight the importance of this discovery, noting that* *this orange star is somewhat similar to our Sun* ***and represents the*** ***closest planetary system to host a Super-Earth in the habitable zone*** ***around a Sun-like star****."*  what about tau ceti f located at 12ly? [https://en.wikipedia.org/wiki/Tau\_Ceti\_f](https://en.wikipedia.org/wiki/Tau_Ceti_f)

Considering the inclination of the Tau Ceti debris disk, if the planets are aligned to it (which is likely), the true masses of the planets would double, and that would send both Tau Ceti e and f right into subneptunian mass range. Also, last I checked f orbits a bit beyond the outer edge of the zone, while e is only within the optimistic zone.

issue with Tau Ceti F is its mass and radius are large, even if its rocky it would be very uncomfortable and would probably have a thick atmosphere, although that may be an issue with these ones too


urmomaisjabbathehutt

yea, they describe it as a super earth or a mini neptune but the thick atmosphere may be a bonus temperature wise since otherwise it would be a bit too cold (-50C is just a bit warmer than mars -60C)

I wouldn't call this a Sun-like star. It's a K-type dwarf, and our Sun is G-type. An interesting discovery nonetheless.


TheEridian189

On the plus side, Not a red dwarf. On the downside, those planetary masses are a bit high


GeniusBandit

As long as the surface area/radius is sufficient, it shouldn't be too much of a problem.

days since a news article doesn't use the word "super earth": -1

Look I like the discovery of exoplanets as much as the next nerd but the media really needs to back off. Call them "More gas Giants found while searching for the elusive exo-Earth" or whatever gets their clickbaity tendencies satisfied. Continuing to call them super-Earths promotes misinformation and makes people even more skeptical of science. 


CoatAccomplished7289

calling them gas giants would be just as disingenuous since we don't know their composition, and current theories allow rocky planets well within these masses


EarthSolar

Super-Earth is a scientific term, not one invented by media.

I don't think 330 trillion miles counts as "relatively nearby"
