New observations confirm Earth-like planet orbiting nearest star
Worlds without end: New observations have confirmed the existence of an Earth-sized planet orbiting the nearest star to our Sun, Proxima Centauri, only 4.2 light years away..
The planet, Proxima b, is estimated to have a mass 1.17 of Earth’s, and orbit the star every 11.2 days. Based on that orbit, the planet is also in the star’s habitable zone. Whether there is life there however remains unknown.
Although Proxima b is about 20 times closer to its star than the Earth is to the Sun, it receives comparable energy, so that its surface temperature could mean that water (if there is any) is in liquid form in places and might, therefore, harbour life.
Having said that, although Proxima b is an ideal candidate for biomarker research, there is still a long way to go before we can suggest that life has been able to develop on its surface. In fact, the Proxima star is an active red dwarf that bombards its planet with X rays, receiving about 400 times more than the Earth. “Is there an atmosphere that protects the planet from these deadly rays?” asks Christophe Lovis, a researcher in UNIGE’s Astronomy Department and responsible for ESPRESSO’s scientific performance and data processing. “And if this atmosphere exists, does it contain the chemical elements that promote the development of life (oxygen, for example)? How long have these favourable conditions existed? We’re going to tackle all these questions.
The research data also suggests there might be another planet in orbit around Proxima Centauri, though this conclusion is very preliminary.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

Rut roh. Alpha Ceti 6.
Huh?
Ceti Alpha VI, a fictional planet mentioned in Star Trek II: The Wrath of Khan?
Every 11 days is very close to the sun, it would pass through atmosphere/solar flares easily.
Mercury takes 88 days to go around the sun, our moon 29 days. The tidal effects alone would most likely melt the surface just like Io which orbits Jupiter every 1.76 days.
We need to start looking for low gravity bodies with high levels of metals.
Bodies massive enough to form themselves round and at most with 1/4 of Earths gravity.
Bodies just large enough to make mining metals easy and with just enough gravity to make refining it easy.
Once we can travel the stars colonies on Earth like planets are a luxury but not a necessity.
Probably tidally locked and perhaps even molten due to tidal flexing. Don’t make vacation plans just yet.
To find Planet X we must follow along all the planets in Alphabetical Order like plAnets A-B-C-D then we find Alpha Centari and the Jupiter 2
