How do other stars affect the Earth or do they have no influence?

At this moment there are no stars — except the sun — that have a significant physical influence on the Earth.They are simply too far away and (therefore) too lightly weak to have that. In theory, however, stars can influence and that can be roughly In two ways:

  1. Gravity
  2. Radiation

Ad.1 — Gravity

When a star gets closer than about 2 light years (a rough estimate), it can affect the Oort cloud.This is a huge stock of small ice-cream objects in a large peel around the solar system. When a passing star interferes with this Oort cloud, this may result in the fact that we are visited over hundreds of thousands of years by a greater number of comets in the inner solar system (near the sun and the Earth). The probability that one of these objects touches the earth is also greater.

Although the chance is literally astronomically small, it could also happen that a star passes much closer to our solar system.If that were to happen, the orbit of the planets, and the Cooper and asteroid belt could be disrupted, with all the serious consequences. What is exactly a safe distance depends on the mass of the star in question. It may be a reassurance to know that we can see such a visit hundreds of thousands of years in advance.

Ad.2 — radiation

When a star explodes within a distance of several dozen light years as a supernova, the radiation released by it can ionize and damage the Earth’s atmosphere.During a supernova explosion, more energy is released within a few weeks than an average star throughout his life (which can be billions of years). In addition, a significant proportion of this energy is released in the form of hazardous high-energy radiation (such as gamma rays). Luckily, there are no stars within about one hundred light years that we expect to explode as a supernova within a few million years.

Certainly they have influence.Not directly of course, but whole tribes come up with the most wacky stories daily or weekly. And Dié often have influence.

The other answers still lack a crucial aspect: the chemical elements.Most of them are created by Super novae. In addition, the heavier elements are formed (nuclear fusion) which then the space is swung. Our solar system has emerged from the resulting dust clouds. The stars that have contributed to the earth have not existed for a long time.

I don’t believe in astrology at all, if that’s what you mean.

In general, the influence is negligible.The gravity of the gas cloud of a fart affects you more than the gravitational force of a star far away. You can’t even see a star when a lamp is near your line of sight. There is much more radiation from a lamp.

There are now no stars in the neighbourhood that can greatly influence us.Long ago or in a distant future they may have much more influence.

A very extreme speculation has been done recently, which disappeared through a supernova forest, which eventually led to the evolution of man.

Did Ancient Super Novae prompt human ancestors to walk upright?
