The Barren Gaseous Planet
Orange Dwarf Star K-Type Main Sequence Star. These stars have masses between those of G-type and M-type dwarfs, and their lifespans are longer than those of Orange Dwarf Star -like Yellow Dwarf Star.
Within the family of stars, the smaller the size, the longer the lifespan. Its longer lifespan than the Sun indicates that its mass is smaller than the Sun's.
The fleet, consisting of more than a thousand spaceships of various types and a thousand Lake-Class Warship, finally activated its Steering Engine. The engines, which had been dormant for fifty years, were restarted. When a ray of light illuminated the dark space, the fleet officially entered the deceleration phase.
The Steering Engine adjusted the Vector Nozzle, and the dust that had accumulated on the engine nozzles, the hull of the warship, and various external equipment due to more than fifty years of steady sailing was shaken off.
Instantly, illuminated by the flames from the nozzles, the massive warships seemed to be shrouded in a thin mist.
Under the control of the coordinated command system, the 1,000 Lake-Class Warship emitted a series of mechanical meshing sounds from their stern Heavy Nuclear Fusion Vector Nozzle, and their long tail flames began to change from horizontal spray to downward spray. At the same time, the Steering Engine at the front of the warships sprayed upwards in unison, and other auxiliary engines also adjusted their spray volume at all times under the precise control of AI.
One by one, the warships flipped over in the starry sky, and soon after, they switched positions, head to tail and up to down.
There is no up or down in outer space. After the warship completed its Attitude Adjustment, what was originally above was now referred to as below by the humans on board.
After this, the tail nozzle adjusted back to a straight jet, and then a larger, brighter jet emerged from the engine nozzle, engulfing the previous jet. At the same time, the Cold Nuclear Pulse Thruster also emitted bursts of nuclear pulses.
With the combined effect of the two types of thrusters, the speed of about a thousand spaceships and a thousand warships dropped rapidly. The scene looked like a group of fireflies with flashing lights, blinking as they entered the Target Star System.
Before the fleet entered the target star system at a reduced speed, the advance probes had already transmitted all the summary data of the target star system to the Lyra.
According to the data transmitted back by the probe, this star system with Orange Dwarf Star as its Main Sequence Star contains only two planets. The outermost planet was discovered first and is a gas giant.
Because it is very conspicuous.
This type of planet is very common in the universe.
In stellar evolution theory, its formation is the same as that of other planets: it is formed by the accumulation of gas and dust left over from the Main Sequence Star its birth.
The scarce matter prevented them from forming stars, and thus they became large Gaseous Planet.
It is conceivable that the formation of Binary Star System and triple star systems in stellar evolution is also due to the same reason.
However, in Binary Star System, the primordial matter is distributed relatively evenly, which makes the Gravity generated by the dust accumulation not much different. Eventually, both are ignited by Nuclear Fusion and evolve into Binary Star System.
Of course, the mass must be sufficient, otherwise it may evolve into Binary Star System of two intertwined stars that are not stars.
In theory, Binary Star System like two Jupiters orbiting alone in the universe exist, but humans have not yet discovered any trace of this type of Binary Star System.
The reason is that these Binary Star System are too special, the conditions for their formation are too demanding, and because they do not emit light, they are difficult to detect like stars.
Therefore, to date, such Binary Star System still exist only in theory, and humans have not yet discovered any trace of them.
If one day humanity discovers the existence of binary or triple star systems in the universe, then humanity's theory of stellar evolution will be further refined.
The same applies to other scientific theories.
When a theory is first proposed, its initial purpose is usually to solve a specific scientific observation phenomenon. At the beginning, a theory can only solve a certain phenomenon, but as people unravel the mystery of the observed phenomenon, the theory will gradually be improved, and it may be able to explain more and more phenomena.
Then, guided by this 'possibility,' humanity purposefully and specifically sought out corresponding phenomena, thereby verifying the theory or even incomplete theories, ultimately turning the theory into a theorem or a formula.
The fleet slowly approached the orbital range of the Gaseous Planet, and people were awakened from hibernation, preparing to begin a new phase of their lives in this Orange Dwarf Star system.
As usual, Yue Yuan arrived at the bridge of the Lyra. However, this time he did not stare at the planetary information on the large screen as before. Instead, he directly observed the Gaseous Planet outside with his naked eye through the outer observation window.
This Gaseous Planet is smaller than Jupiter and does not have Jupiter's rings. It is a very clean Gaseous Planet.
It's so clean there isn't even a single satellite.
The fact that a Gaseous Planet has no moons is quite unexpected for astronomers. Previously encountered Gaseous Planet typically have at least two large moons, and countless smaller, non-spherical moons.
But this Gaseous Planet doesn't even have a single moon.
Logically speaking, such a discovery is quite normal. If a non-professional saw it, they would at most glance at it as a scenic view and then move on. Even someone with some basic astronomical knowledge would only find it a bit amazing.
However, it was truly strange for astronomers.
Therefore, after the probe transmitted data about this Gaseous Planet, three different viewpoints emerged among the team of human astronomers.
The first view holds that when Star System was first formed, there were actually many satellites. However, during the long history of star evolution, the Gravity interaction between multiple stars made the orbits of the satellites unstable, and eventually, over a long period of time, they all fell into the Gaseous Planet.
However, this explanation fails to account for why Gaseous Planet do not have rings.
The reason is naturally the Roche Limit. If the original moons were later swallowed by Gaseous Planet due to their fall, they would have been torn apart by the unbalanced Gravity when they entered the Roche Limit the gas giant. Over time, these torn pieces of matter would form a ring in the orbit of the Gaseous Planet.
The second view is that at the beginning of the Star System, this Gaseous Planet also had many moons, but at some point in the universe, an Alien Civilization came and mined all of these planets.
The third viewpoint belongs to the natural evolutionary cycle, which states that this Gaseous Planet had no moons at the beginning of the Star System's formation.
In an effort to find the answer, astronomers launched more than a dozen probes to orbit the Gaseous Planet before the fleet had even fully slowed down, specifically to explore this phenomenon.
These probes will conduct a variety of experiments in orbits around Gaseous Planet, including collecting and analyzing dust clouds in various orbits, exploring low Earth orbits, and conducting crash tests.
The so-called drop test is exactly what it sounds like: a specially designed probe is dropped into a gas giant and various information is collected during the fall.
