How many hidden planets could there be in our solar system?

Published

Scientists are anticipating that there might be Jupiter and Uranus-sized planets hidden in our solar system, possibly at the edge of it, the Independent reported Monday.

Scientists are predicting that the planet may be much farther than the planet X — those planets that live beyond Neptune.

Researchers anticipate that such a planet may be trapped in the Oort Cloud — a shell theorised by astronomers marking the border of the gravitation of the sun and associated satellites.

According to the experts, there could be more interstellar objects on this edge of the Solar System than earlier thought.

With the help of complex computer simulations, scientists assessed how solar systems tend to throw off large planets, and also how a planetary system could catch one such planet.

As such a planet would need kinetic energy to leave the gravitational orbit of its axis star, it also needs a similar amount of energy for another system to bring it in.

Simulations suggested that a small number of such space encounters may end up with a star’s gravitational pull catching a cast-away planet and making its own.

Astronomers said: “This is more likely to happen when such a planet drifts close to a star system’s outer edge Oort cloud.”

Researchers estimated that “one in every 200-3000 stars could host an Oort cloud planet.”

“If the Solar System’s dynamical instability happened after birth cluster dissolution, there is an about 7% chance that an ice giant was captured in the Sun’s Oort cloud,” scientists wrote in the study.

But, they also said this prediction is likely an overestimate as the estimate does not account for instabilities that take place at the early stages of a solar system that could affect its star birth cluster, or planet stripping from passing stars.

Relying on the observation, scientists maintained that Oort Cloud planets at the edge of the Solar System are more likely to be adopted from interstellar space rather than being an offspring of the Sun

Users of WhatsApp will soon be able to lock chats on connected devices.

Additionally, linked devices will now have access to the conversation lock feature. Users of WhatsApp will also soon have the option to tag their contacts in status updates.

Notably, WhatsApp users can link their devices to log in to the same account on different devices. However, several functions, such as conversation locks and status updates, are not accessible on the secondary devices.

Even if they are locked on the main conversations, anybody can still access your private chats on a connected device. WhatsApp is currently working on adding Chat Lock capability to connected devices in order to address this.

The chat lock feature on WhatsApp will soon be available on connected devices.

Prior to this, it was claimed that WhatsApp, which is owned by Meta, was developing new personalisation options for an iOS beta.

According to WABetaInfo, an update tracker portal for the instant messaging network, WhatsApp for iOS users will soon get the option to modify both the conversation bubble’s colour and the app’s primary colour scheme.

A feature that let beta testers choose the primary colour scheme of the WhatsApp iOS app from a selection of five colours was first tested back in January.

The instant messaging app is testing a feature that lets users change the colour of chat bubbles within conversations, though, in a new beta edition.

Moon train operations are planned by NASA.

The goal is to construct the first lunar train system, which will enable safe, independent, and effective cargo transportation on the moon, according to robotics specialist Ethan Schaler of NASA’s Jet Propulsion Laboratory in Pasadena, California.

He went on, “The day-to-day functioning of a sustainable lunar base in the 2030s will depend heavily on a robust, long-lasting robotic transport system.”

The Flexible Levitation on a Track, or FLOAT, is the name of the proposed lunar rail system. According to NASA, the establishment of a railway system on the moon is “critical to the daily operations.”

According to the space agency, the primary objective of FLOAT is to offer transportation services in regions of the moon where astronauts are engaged in activities. To do this, cargoes of lunar soil and other materials will need to be transported to various regions of the moon.

Each robot will be able to transport cargo of various sizes and shapes at a pace of roughly 1 mph (1.61 km/h), according to Dr. Schaler.

Notably, NASA also declared new initiatives last month to create and test new vehicle models intended for moon exploration.

Pakistan’s lunar mission (ICUBE-Q) entered orbit around the moon on Wednesday.

Pakistan’s historic lunar mission (ICUBE-Q) launched from Hainan, China, on Friday aboard China’s Chang’E6 spacecraft.

According to the IST, the satellite ICUBE-Q was planned and developed in partnership with China’s Shanghai University SJTU and Pakistan’s national space agency SUPARCO.

The ICUBE-Q orbiter is equipped with two optical cameras to image the lunar surface. ICUBE-Q has now been integrated into the Chang’e6 mission after successfully qualifying and testing it.

Chang’e6 is the sixth lunar exploration mission launched by China.

The launch event was streamed live on the IST website and social media platforms. Chang’6, China’s Lunar Mission, will land on the Moon’s far side to collect surface samples before returning to Earth for further research.
