Now two astronomers from the Complutense University of Madrid, the brothers Carlos and Raúl de la Fuente Marcos, together with the researcher Sverre J. Aarseth of the University of Cambridge (United Kingdom), have analyzed
for the first time the nearly 340
objects of the
solar system with hyperbolic orbits (very open V - shaped, not the typical elliptical), and
in doing so they have detected that the trajectory of some of them is influenced by the passage of Scholz's star.

solar system's early history.
Viewed from a planet at Earth's orbital distance around Alpha Centauri A, stellar companion B would provide more light than the full Moon does on Earth as its brightest night sky
object, but the additional light at a distance greater than Saturn's orbital distance
in the
Solar System would not be significant
for the growth of Earth - type life.
Many scientists believe the Earth was dry when it first formed, and that the building blocks
for life on our planet — carbon, nitrogen and water — appeared only later as a result of collisions with other
objects in our
solar system that had those elements.

Light from the
