Discovery of the baby solar system record

Scientists have discovered that a solar system is "cramped" most when 5 planets orbiting a star with orbits closer from Earth to the Sun at least 12 times.

LiveScience said astronomers discovered this exotic solar system through NASA's Kepler telescope. They analyzed the planetary system revolving around the star KOI-500, a star whose mass is equivalent to the sun but the diameter is only ¾ and the age of only about 1 billion years, less than half the age of the sun. we.

The most cramped "KOI-500" star ever.

KOI-500 is about 1,100 light-years away from the constellation Lyra. This is a super-cramped planetary system, even the most 'crammed' ever discovered when there are at least 5 planets orbiting KOI-500 at a distance of 1.3 - 2.6 times Left size land.

It is because the planets' orbits are so close to KOI-500 that their "year" - the time needed for them to orbit this star only lasts 1.0; 3.1; 4.6; 7.1 and 9.5 Earth days. They are so close to each other that the attraction of each other is both pulling and moving the trajectory. However, these trajectories appear to be very stable - they are not at risk of colliding or pushing apart from KOI-500, astronomer Ragozzine revealed on Space.com.

Ragozzine believes that initially, the planetary system surrounding KOI-500 is wider but due to the gravitational interaction between the planets, plus the pressure from the gas, the planetary system is squeezed to the present.

In addition to finding more and more new solar systems, scientists also found that most systems have much more orbit close to asteroids than the distance from any solar system. Sun. Scientists are still unable to explain why the solar system is so widespread and so unusual.
