Proxima Centauri System.
A planet with roughly 1.3 times Earth's mass swept swiftly along its orbit, 0.05 astronomical units from Proxima Centauri.
It was Proxima b, the homeworld of the Proxima Centauri Civilization.
Its orbital semimajor axis was just 0.05 astronomical units, about 5% of Earth's. By comparison, even Mercury, the first planet in the Solar System, had an orbital semimajor axis of 0.39 astronomical units.
Unlike the Sun in the Solar System, Proxima Centauri, the primary star of the Proxima Centauri System, had only one-eighth the Sun's mass.
It was merely a red dwarf.
That was precisely why a planet so close to Proxima Centauri had a chance to nurture life.
The surface of Proxima b.
After transmitting that string of information to the Solar System 4.22 light-years away, the signal receiver Atoka returned to his usual routine.
There was nothing else he could do. Given the speed at which electromagnetic waves traveled, they would have to wait at least 8.44 years before they could possibly receive a reply from the advanced civilization in the Solar System.
So, for now, his entire job consisted of continuing to check the data sent back by each probe.
The workload was light. In his spare time, he could even take advantage of his position to indulge his hobby.
Stargazing.
Observing Proxima Centauri through an optical telescope was his favorite way to spend his breaks.
Today, as usual, after checking the data from the other probes, he quietly operated the optical telescope fitted with filters, pointing it at Proxima Centauri, 0.05 astronomical units away.
Atoka stared blankly at the slowly burning ball of fire displayed on the instrument before him.
This was the star their civilization depended on for survival!
When he thought of how his civilization's technological development had stagnated for centuries,
