Aditya L-1: India’s Solar Mission Reaches Sun’s Orbit

India’s first mission to the Sun, Aditya-L1 reached its final destination in space on January 6, 2024. The spacecraft has positioned itself at Lagrange Point 1 in the Sun’s orbit. Aditya, named after the Hindu Sun God, has travelled around 1.5 million km from Earth. It is now at a point where the gravitational forces of both celestial bodies cancel out, allowing it to remain in a stable halo orbit around the Sun.

The Indian Space Research Organisation’s Aditya-L1 mission was launched on September 2, 2023 and took four months to reach the Sun’s orbit. The Indian scientists believe that now since Aditya-L1 is in the Sun’s orbit, it will be able to watch the Sun constantly and carry out scientific studies. Aditya L-1 will spend five years in space observing solar activity, solar wind, and solar flares – and their effect on Earth.

The Indian space agency has also said that some of the instruments on board the satellite have already started work, gathering data, and taking images.

India’s Prime Minister Narendra Modi called the mission “a landmark” and an “extraordinary feat”.

Is There A Mystery Planet In Our Solar System?

Researchers may have discovered proof of a new planet similar to Earth.

A team of astronomers in Japan, including those from the country’s National Astronomical Observatory, believe that there is an unknown planet that may be circling the Sun in an orbit past Neptune. As of now, we know for sure that there are eight planets in our solar system. Their order from nearest the Sun to furthest away goes: Mercury, Venus, Earth, Mars, Jupiter, Satum, Uranus, Neptune and then a possible Planet Nine.

The published research suggests that this possible Planet Nine, could be hiding in the Kuiper Belt. The researchers found that the way that some of the objects in the Kuiper Belt behave suggests there could be a small planet among them. The astronomers think this new planet could be three times as big as Earth but it would not have life as we know it, because the temperatures would be too cold. The team say finding this new discovery near the Kuiper Belt, could lead to finding more possible planets.

According to NASA, the Kuiper Belt is a doughnut shaped region of icy bodies beyond the orbit of Neptune – the eighth and most distant planet in our solar system.

Did You Know?

For more than 70 years, Pluto was considered to be the ninth planet in our solar system. However, in 2006, the International Astronomical Union downgraded Pluto to a dwarf planet. A dwarf planet orbits the sun just like other planets, but it is smaller.
