With the advancement of technology, every year we learn new and interesting information about space. Especially in recent years NASA and Elon Musk SpaceXCollaborating with , unlocks many mysteries about our universe. As all these studies continue, a study published in 2019 by three scientists opened a new window in the scientific world.
A simulation developed by three scientists named Tom Stockman, Gabriel Monroe and Samuel Cordner, contrary to what was known until that day, is the closest planet to Earth. Mercury revealed that. NASA calculations, on the other hand, show that the closest planet is Venus, as also found on the official site. In light of all this information,Which planet is closest to Earth?’ Let’s look for an answer together.
According to the information on the official website of the National Aeronautics and Space Administration (NASA), Venus is the closest planet to Earth. However, in a new study published in 2019 by three scientists, the planet is closest to Earth for the longest time Mercury was declared.
A simulation has been developed by these three scientists that makes predictions about distances based on a period of 10,000 years using Python to more accurately determine which planet is closest to Earth. These simulation results were then compared to the results of PCM (treating the orbits of two objects as circular, concentric and concentric) and conventional computational methods. The simulation results are compared with traditional calculation methods. up to 300% accurate, with PCM results from 1% showed less deviation. As a result, because the simulating planets are positioned relative to their orbits, from Mercury It turned out to be closer to Earth than Venus.
If you examine the solar system in detail, from Venus you can also see that Mars seems to be the planets with the shortest distances from Earth. So, by calculating the average distance between Earth-Mars and Earth-Venus, and then subtracting the radii of the planets, you can find that the closest planet to Earth is Venus.
While this formula is not fundamentally wrong, it only measures the shortest possible distance between two planets. Basically, it reveals how close the planets will get to Earth during their orbits, but these planets can be much farther from Earth during their off-orbit time. Therefore to the world nearest planet To find out, it is necessary to take into account the average distances of the planets along their orbits.
To get a clear answer to this question, we need to see which planet is closest to Earth on average. When we calculate this from Mercury In fact, we see that it is the planet that spends the most time at the closest distance to Earth. This is because of all the planets in our solar system, Mercury has the smallest orbit. So while Mercury never gets as close to Earth as Mars or Venus, it never gets as far away as these rovers.
Also, this small orbit of Mercury makes it the closest planet to all the planets in the solar system. The same method used to calculate Mercury’s distance from Earth also applies here. Although Mercury is never too close to these planets in the solar system, it is not too far away.
We have compiled the above data based on NASA’s studies. Distances between planets are constantly changing, as each planet depends on where it is in its orbit around the sun. Sometimes these distances are close, sometimes they are quite far. This is because planets have elliptical orbits. To give an example Mercury The distance between the planet and Earth can vary from 82.5 million km at the closest point to 216.3 km at the furthest point.
That is, any two planets are closest when they are on the same side of the sun. Therefore, talking about the distance between two planets is based on the average distance between them. These distances are usually shown in kilometers, miles, or astronomical units (AU). Already at this point, due to the calculation differences, the nearest planet There are disagreements about which one.
Discovered by German astronomer Johann Gottfried Galle on September 23, 1846, Neptune reaches Earth It’s the furthest planet. It is named after the sea god because of its bluish ocean color. Neptune is about 30 times farther from the Sun than Earth and takes about 165 Earth years to complete its orbit. Because it rotates on its axis faster than the Earth on Neptune a day is only about 16 Earth hours.
Launched as part of the US Voyager program in 1977, the Voyager 2 spacecraft took 12 years to reach Neptune. This is reported by the National Air and Space Museum. from Neptune The average temperature in the atmosphere is -225 degrees Celsius. The biggest reason for this is that it is quite far from the sun. It takes about 4 hours for a light from the planet, which is 4.5 billion kilometers from the sun, to reach Earth Neptune, which is about four times as wide as Earth, is the largest in the solar system with a radius of 24,674 kilometers and a diameter of 49,244 kilometers. is the fourth planet.
