Astronomers discover 840 small planets beyond Neptune



The universe is an incredibly large place. Despite extensive efforts over the years, many of its regions have still not been explored or explored. Now researchers have discovered and confirmed 840 small worlds in a remote, hard-to-reach area beyond Neptune. This is the largest single find of planets ever made and increases the number of distant planets around the sun by 50%.

Mapping the outer regions of our solar system is not an easy task. Our solar system did not always look like it does today. The vast majority of small planets – including some of the worlds we've just discovered – moved away from the sun until they settled in their current locations. Besides, these planets are extremely small and weak. The discovery of these planetary populations allows us to reconstruct the history of our solar system.

The latest discovery is the result of a five-year project called OSSOS (Outer Solar System Origins Survey). Using the imaging camera installed on the Canada-France-Hawaii telescope in Hawaii, the researchers looked for faint, slow-moving points of light in eight large sky areas near the planets and away from the dense stars of the Milky Way discovered 840 small planets in Distances between six and 83 astronomical units (au). Astronomical unit is the average distance between the Earth and the Sun that is used to measure distances within our solar system.

Earliest reviews of distant areas were quite uncertain. When the path of a minor planet was discovered in the sky, telescopes often could not find it, which in turn can lead to confusion about the populations. However, a recent study often photographed 840 objects over several years, allowing researchers to understand how the planets formed and then move out of the sun. With OSSOS researchers were able to observe planets in the vastness of our solar system with an unprecedented level of detail.

Of these planets, 436 small worlds with nearly perfectly round, flat orbits are found in the Kuiper Belt at 43 to 45au and 31

3 are resonant trans Neptune objects. They exist as far as an incredible 130au and are much more common than previously thought. These discoveries include nine small worlds with incredibly distant orbits. These planets are never closer to the sun than Neptune's orbit and take up to 20,000 years to complete an orbit around our star. Their presence indicates that hundreds of thousands of such planets lurk in our solar system.
