If there is no Jupiter, the chances of Earth suffering from the same meteorite that killed the dinosaurs,
temperature on Earth just right for life to exist,
Every 26 million years or so, it collides with the Oort cloud region at the edge of the solar system,
If Earth were in the orbit of Venus or Mars, it would be too hot or too cold for life to exist,
The sun has a companion star called Nemesis,
This means that microbes may be able to take advantage of this process,
faster than the relative velocities of two stars at close encounters,
Comets from alien galaxies are the main cause of extinction on Earth,
It will be once every 10,000 years, then no advanced life can evolve on the earth at all,
The existence of life on earth and the evolution of advanced life is also related to the fact that the earth has a Jupiter,
The solar system will be bombarded by such comets,
Mass extinctions on Earth seem to happen every 20 to 40 million years,
Dust kicked up by comet impacts can be pushed by the pressure of sunlight,
This number is very close to the cycle of mass extinctions on Earth,
Flying outward at a speed of 108,000 kilometers per hour,
Jumping from the solar system to another planetary system passing by,
Frequent exchange of material with other planetary systems,
It is precisely because of Jupiter that has the largest mass and volume that it attracts many meteorite impacts to the earth,
