The closest planet to the sun
The closest planet to the sun, is one of the celestial bodies associated with the solar system in space, which is distinguished from other similar bodies and astronomy lovers usually want to know a lot of information regarding it, as its name, attributes and some things associated with it, which was revealed by the US NASA website. For cyberscience, in a detailed report.
The closest planet to the sun
Andnearest planet The sun and the smallest in the group is Mercury, which appears slightly larger than the moon of the planet Earth, and when observing it, the sun appears three times larger than it appears when looking at it from our planet, and the light of the most famous star is seven times brighter.
Although Mercury is the closest planet to the sun, it is not the hottest planet in our solar system, but rather it is related to Venus, due to its dense atmosphere, due to Mercury’s apparent elliptical orbit in the form of an egg, and its slow rotation. other parts of the planet’s surface, as the same thing happens in the opposite direction at sunset.
Things you need to know regarding the planet Mercury
There are a number of facts related to the planet Mercury, which we explain with the following lines:
Mercury is the smallest planet in the solar system and slightly larger than Earth’s moon.
Mercury is the planet that orbits the closest planet to the sun.
– عطارد It is the fastest planet in our solar system, as it travels through space at a speed of approximately 47 kilometers per second, as the closer the planet is to the sun, the faster it travels, and the reason is that Mercury has the shortest distance to move around the sun, where the shortest year among all the planets in our solar system is 88 days .
– Mercury is a rocky planet, also known as a terrestrial planet; It has a hard surface full of craters, much like Earth’s moon.
Mercury’s thin atmosphere or exosphere is made up of oxygen (O2), sodium (Na), hydrogen (H2), helium (He) and potassium (K).
Mercury has no moons.
There are no rings around Mercury.
Life as we know it is unlikely to appear on Mercury due to solar radiation and extreme temperatures.
Standing on the surface of Mercury at its closest point to the sun, our star would appear three times larger than it appears on Earth.
Mercury is aptly named for the fastest of the ancient Roman deities.
Mercury has a diameter of 2440 km, which is just over 1/3 the width of the Earth; If Earth was the size of a nickel, Mercury would be the size of a raspberry.
At an average distance of 58 million km, Mercury is 0.4 AU from the Sun.
The surface of Mercury is similar to the surface of the Earth’s moon, and has been distorted by many craters resulting from the collision of meteorites and comets.
Although Mercury’s magnetic field at the surface has only 1% of the force of Earth, it interacts with the magnetic field of the solar wind to form magnetic cyclones sometimes that transfer hot solar wind plasma fast to the surface of the planet, where when ions collide with the surface , they cut the neutrally charged atoms into a ring high in the sky.
And during a study published in October 2021, experts said that despite Mercury’s extreme proximity to the sun, and extreme temperature swings, humans can technically walk on the planet’s surface, but the real problem will be finding a way to safely touch, as there is no atmosphere to use it. It means more reliance on heavy fuel to control speed, according to the Russia Today website.
