The sun is by far the most massive object in our solar system, accounting for 99.8 percent of its total mass. It emits the majority of the heat and light necessary for life on Earth and possibly elsewhere. The orbits of planets around the sun are ellipses, with the sun slightly off-center of each ellipse. NASA has a fleet of spacecraft, such as the Parker Solar Probe, observing the sun to learn more about its composition and to improve forecasts of space weather and its impact on Earth.
As The Sun is so destructive and powerful, people wonder whether any planet could survive near the sun, so let’s check out Which Planet Formed Near The Sun Where The Solar System’s Temperatures Were Very High?
Which Planet Formed Near The Sun?
The correct answer to this question is Mercury. Mercury is the closest planet to the sun as well as the smallest planet in the solar system, measuring only slightly larger than Earth’s moon. Mercury travels around the sun in 88 days due to its close proximity to our star (about two-fifths the distance between Earth and the sun).
The temperature of Mercury varies dramatically between day and night. During the day, mercury temperatures can reach 840 F (450 C), which is hot enough to melt lead. Meanwhile, temperatures at nightfall to minus 290 F (minus 180 C). MERCURY FACTS – DECLARATION: Known to the ancient Greeks and visible to the naked eye.
– Named after the Roman gods’ messenger
– Diameter: 3,031 miles (4,878 kilometers).
– Orbital period: 88 Earth days
– Duration: 58.6 Earth days
– There are no moons.
The atmosphere of Mercury is extremely thin and primarily composed of oxygen, sodium, hydrogen, helium, and potassium. Because its atmosphere is so thin that it cannot absorb incoming meteors, its surface is dotted with craters, much like our moon’s. NASA’s MESSENGER spacecraft made incredible discoveries that surpassed astronomers’ expectations during its four-year mission. Among these discoveries were the discovery of water ice and frozen organic compounds at Mercury’s north pole and the fact that volcanism played a significant role in shaping the planet’s surface.

How Was Mercury Formed?
Mercury is an exceptional planet in many ways, and the process by which it formed is no exception to this rule. It is estimated that it was created approximately 4.6 billion years ago, during the early stages of the formation of our solar system. Mercury originated from the same cloud of gas and dust that was responsible for the formation of the sun. The sun was initially a dense core of gas that began to collapse under the influence of its gravity.
Recently some amazing photos of the planet Mercury were making news around the globe. Below you can see that photo in a Tweet by Rappler.
The core began to spin as it collapsed, which resulted in the formation of a disk of gas and dust that, over time, led to the construction of the planets that make up our solar system. Because of the planet’s close proximity to the sun, the intense heat and radiation from the star caused the lighter elements, such as hydrogen and helium, to evaporate from the planet’s surface, leaving behind the dense, rocky core that we see today.
While researchers are still working to piece together the specifics of how Mercury came to be, it is abundantly clear that this diminutive planet harbors a wealth of information regarding the origins of our solar system.
Conclusion: Our solar system’s largest object, the sun, is crucial. NASA’s fleet of spacecraft is studying it because it provides Earth’s heat and light. Mercury, despite the sun’s power, formed near it. Despite its small size and intense temperature variations, Mercury holds a wealth of information about the early solar system. Its rocky core, formed by the sun’s heat and radiation evaporating lighter elements, reveals planet formation. Mercury shows that our solar system is diverse and complex, even though the sun is the most powerful.
