Are you interested in planets and interested in learning about astronomy? Guess which planet is closest to our Earth? Soon, we will reveal to you the Top 10+ nearest planets to earth.
Mercury
Mercury can be at a distance of 77.3 million km from Earth. Mercury rotates on its axis three times in two orbits around the Sun, taking the fixed stars as the frame of reference. If viewed from the Sun, in a reference frame that rotates in a moving orbit, Mercury only rotates once in two orbital periods of the planet. This exact ratio is due to the effect of tidal locking. If a person stands on Mercury, they will only see the Sun move once in the sky, or only 1 “day” in 2 “years” of Mercury.
One “year” passes each “night” of Mercury, while the Sun is below the horizon, so the surface temperature drops very low. During the one-year period of “day”, the Sun moves very slowly across the sky from the eastern horizon to the western horizon, while the planet has completed one orbit around the Sun, passing both perihelion and aphelion. At perihelion, the intensity of light hitting the planet’s surface is twice as high as when it is at aphelion. There are points on the surface that are continuously illuminated by the Sun during the “day” when it is at perihelion. These places thus become very hot. Places, where the Sun is high in the sky during planetary aphelion, have lower temperatures than at perihelion.
Venus
Venus is only about 41 million kilometers from Earth when it is closest to Earth, closer than any other planet in the Solar System. And when it is at its furthest, it is also only about 261 million kilometers from Earth. It is the second planet in the solar system, orbiting itself every 224.7 Earth days. Because Venus is the inner planet from Earth, it never appears in the sky too far from the Sun: the elongation peaks at 47.8°. Venus reaches its greatest brightness right near sunset or dawn, so folk also call it Evening star, when the planet appears at dusk, and Morning star, when this planet appears at dawn. bright.
Venus is classified as a terrestrial planet and is sometimes considered a “sister planet” to Earth due to its size, gravitational acceleration, and orbital parameters similar to Earth’s.
Mars
Mars is 33.9 million miles from Earth. Mars or Mars is the fourth planet from the Sun in the Solar System. It is often referred to as the “Red Planet” because iron oxide is so abundant on the planet’s surface that it appears to have a distinctive red color. Rocky planet – Mars has a very thin atmosphere. In addition, on its surface there are craters, valleys, deserts and ice sheets. The rotation and periodicity of the seasons on Mars are quite similar to those of Earth due to the tilt of the axis of rotation.
Moon – Top 10+ Nearest Planets to Earth
This planet is 384,400 km from Earth. The Moon is the only planet we can see from Earth without a telescope. It is also the only satellite of the Earth. The luminosity of the moon as seen from Earth is second only to the Sun. This is a quasi-spherical object with a size of about 27% of the Earth’s size and a mass of about 1.23% of the Earth’s mass. The Moon is rich in silicate rock and has no significant atmosphere, hydrosphere, or magnetosphere.
One widely accepted theory is that the Moon formed more than 4.5 billion years ago, not long after the Earth formed, from material ejected from a massive collision between the Earth and a celestial body. The hypothetical Theia is the size of Mars.
Sun
The Sun is 149.6 million kilometers from Earth. The Sun is the star at the center of the Solar System, accounting for about 99.8% of the Solar System’s mass. The Earth and other celestial bodies such as planets, asteroids, meteorites, comets, and dust orbit the Sun. The average distance between the Sun and the Earth is approximately 149.6 million kilometers (1 AU), so it takes 8 minutes and 20 seconds for sunlight to reach Earth. Over the course of a year, this varies from 147.1 million kilometers (0.9833 AU) at perihelion (about January 3), to as far as 152.1 million kilometers (1.017 AU) at aphelion. (around July 4th). Solar energy in the form of light supports most life on Earth through photosynthesis and controls Earth’s climate and weather.
Jupiter
The distance from Earth to Jupiter is 588 million km. Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is a gas giant with a mass of one-thousandth of the Sun but two and a half times the total mass of all the other planets in the Solar System combined. Jupiter is classified as a gas giant along with Saturn (Uranus and Neptune are classified as ice giants). These two planets are sometimes called Jupiter-type planets or outer planets.
This planet was known to ancient astronomers and is associated with myths and religious beliefs in many cultures. The Romans named the planet after the god Jupiter, the most important of the gods. The name in Chinese, Korean, Japanese, and Vietnamese of this planet is based on the “wood” element in the five elements. As seen from Earth, Jupiter has an apparent magnitude of −2.94, bright enough to cast a shadow; and is the third brightest object in the night sky after the Moon and Venus. (Mars is almost as bright as Jupiter when Mars is in opposite positions in its orbit to Earth.)
Saturn – Top 10+ Nearest Planets to Earth
Saturn is about 1.2 billion km from Earth. Saturn is the sixth planet by mean distance from the Sun and the second-largest in diameter and mass, after Jupiter in the Solar System. Saturn is a gas giant with an average radius 9 times that of Earth. Although the planet’s mass is 95 times that of Earth, at 763 times larger, Saturn’s average density is only one-eighth that of Earth.
Saturn’s internal structure probably consists of a core of iron, nickel, and rock (compounds of silicon and oxygen), surrounded by a thick layer of metallic hydrogen, an intermediate layer between liquid hydrogen and liquid helium, and an atmosphere. top side. The planet’s pale yellow color is due to the presence of ammonia crystals in the upper atmosphere. Electric currents within the metallic hydrogen layer are responsible for the fact that Saturn has a planetary magnetic field with a strength slightly weaker than that of Earth and one-twelfth that of Jupiter. The planet’s upper atmosphere is uniform in color and appears calm compared to Jupiter’s turbulent atmosphere, although it also has strong storms. Wind speeds on Saturn can reach 1,800 km/h, faster than on Jupiter, but not as fast as those on Neptune.

Uranus
The distance from Earth to Uranus is 2.52 light hours. Uranus is the seventh planet from the Sun; is the third largest radius and fourth most massive planet in the Solar System. Uranus has a similar composition to Neptune. Both have different chemical compositions than the two larger gas giants, Jupiter and Saturn. Therefore, astronomers sometimes include these planets in the list of “ice giants”. Uranus’ atmosphere is similar to that of Jupiter and Saturn in basic components such as hydrogen and helium. The other is that they contain many volatile compounds such as water, ammonia, and methane along with small amounts of hydrocarbons. This planet has the coldest atmosphere of any of the planets in the Solar System, with a minimum temperature of 49 K (−224 °C). It has a complex cloud layer structure. It is likely that the lowest clouds contain mainly water while methane is predominant in the upper clouds. In contrast, the structure inside Uranus consists mainly of an ice and rock core.
Neptune
The planet is located 4.41 billion km from Earth. Neptune is the eighth and furthest planet from the Sun in the Solar System. It is the fourth-largest planet in diameter and the third-largest by mass. Neptune has the highest density of any gaseous planet in the Solar System. Neptune is 17 times the mass of Earth and slightly more massive than Uranus (approximately 15 times that of Earth). Neptune orbits the Sun at an average distance of 30.1 AU, about 30 times the Earth-Sun distance. Neptune is named after the Roman god of the sea (Neptune). It has the astronomical symbol ♆, which is a stylized representation of Neptune’s trident or the Greek letter psi.
The Pluto – Top 10+ Nearest Planets to Earth
Pluto is the second most massive known dwarf planet in the Solar System (after Eris) and the tenth most massive object directly orbiting the Sun.
Formerly classified as a planet, Pluto is now considered the largest member of a separate region known as the Kuiper Belt. Like other members of this belt, it is mainly composed of rock and ice and is quite small in size: approximately one-fifth the mass and one-third the volume of Earth’s Moon. Pluto has an orbit with great eccentricity and is very tilted. Its eccentricity makes it possible to be 30 to 49 AU (4.4–7.4 billion km) from the Sun, so Pluto is sometimes closer to the Sun than Neptune. Pluto and its largest moon, Charon, are often considered to be a binary system because the centers of mass of their orbits do not lie within any one object. The International Astronomical Union (IAU) has yet to formalize a definition for binary dwarf planetary systems, and until they adopt such a decision, Charon will still be classified as a satellite of Pluto King. Pluto also has three other smaller moons, Nix, Hydra, discovered in 2005, and P4 discovered in 2011.
