Scientists Say Mercury Which Was Once as Big as The Earth

In the celestial neighborhood that we call our solar system, each planet has its own unique story. One of the most enigmatic celestial bodies is Mercury, the sun's closest companion. Recent discoveries suggest that this tiny planet could have been as large as Earth in its early life. Mercury, named after the Roman deity Mercury, the messenger of the gods, is a fascinating planet, both in terms of its physical characteristics and its orbital behavior. Mercury is the smallest planet in our solar system and also the closest to the sun. Despite its small size, the planet has a massive iron core, and its surface is pockmarked with craters, similar to our moon.

Two Airplane-Sized Asteroids to Skirt Past Earth, Reports NASA

The National Aeronautics and Space Administration (NASA) has announced that two asteroids, each comparable in size to an aircraft, are set to swoosh past our planet. NASA's website recently revealed that a duo of airplane-sized asteroids will perform a close flyby of Earth today. Intriguingly, a building-sized asteroid is also expected to approach our planet on the same day. Following this, two more asteroids will draw near to Earth on Monday. The three asteroids set to come close to Earth have an average size of around 73 meters. Any celestial object larger than approximately 150 meters and capable of approaching Earth within a certain distance is termed a potentially hazardous object by NASA. According to NASA's data, the asteroid 2024 FG will approach Earth up to a distance of ...
