🌑The sun likely had a twin during its formation billions of years ago.
🌮The existence of the twin, known as Nemesis, is still a topic of debate.
🐳Nemesis, if it exists, could be a brown or red dwarf or even a rogue planet.
🌌The idea of Nemesis came from the observation of cyclic mass extinctions on Earth.
🌠While the existence of Nemesis is uncertain, the concept of the sun's lost twin remains intriguing.
What evidence is there for the existence of the sun's lost twin?
—There is no direct evidence of the sun's lost twin, but the observation of cyclic mass extinctions on Earth sparked the idea of Nemesis.
What could the sun's lost twin be?
—If the lost twin exists, it could be a brown or red dwarf, a depleted star, or even a rogue planet.
Why is it difficult to find the sun's lost twin?
—Finding the sun's lost twin would require identifying all stars similar to our sun across the Milky Way galaxy, a nearly impossible task.
How did the sun's lost twin affect Earth?
—The gravitational influence of the sun's lost twin could have caused disturbances in Earth's climate, tectonic activity, and mass extinctions.
What can we learn from the sun's lost twin?
—Studying the sun's lost twin would provide valuable insights into the formation and evolution of our solar system.
