why do mercury and venus not have moons
As the closest planet to the Sun, Mercury is highly influenced by the stars gravityand so
Mercury likes to keep things simple. Given its small size, Mercury does not exert a strong gravitational field, making it difficult for the planet to hold onto anything in orbit. In the comic strip "Calvin and Hobbes," Calvin and his classmate Susie give a presentation about Mercury, in which Calvin's contribution is full of questionable information: "The planet Mercury was named after a Roman god with winged feet," says Calvin. Itll be the best Mercury elongation of the year.
The reason why these planets have no moons is because they are so close to the sun, that the sun would probably pull them away. If a moon were too close to the planets, it would fall within the Roche limit and be torn apart by tidal forces. An artistic interpretation of Curiositys view high up on a Martian mountain was created by mission team members.
Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. 
That website states that Venus is believed to have had a moon at some point in the solar system's long existence. But newer estimates made with help from computer models paint a different portrait. 
WebVenus and Mercury do not have moons because they are closer to the Sun than Earth. 
Venus has been known since ancient times because it can be seen easily without a telescope.
Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. ESA's BepiColombo is on its wayto Mercury.
The rovers self-driving capabilities will be put to the test as it begins a record-breaking series of sprints to its next sampling location. Johns Hopkins University MESSENGER Mission Site, Science Writers:
This year, the minimum extent of Arctic sea ice dropped to 1.82 million square miles (4.72 million square kilometers).
Any moon with too great a distance from these planets would be in an unstable orbit and be captured by the Sun.
Two NASA missions have explored Mercury: Mariner 10 was the first to fly by Mercury, and MESSENGER was the first to orbit. Quick History. World Atlas goes on to state that Venus, which also has no moons, is a slightly different case. Plus Mercury is extremally small, so its tiny gravity VS the suns is huge. 
World Atlas goes on to state that Venus, which also has no moons, is a slightly different case. Researchers will use Webb to observe 17 actively forming planetary systems. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system 88 days.
Thats primarily because theyre too small and too close to the Sun to retain a moon, and Venuss motion is too unusual.
It is the closest planet to the Sun, but its actually not the hottest.
Scores of science fiction writers have been inspired by Mercury, including Isaac Asimov, C. S. Lewis, Ray Bradbury, Arthur C. Clarke, and H. P. Lovecraft.
However, after only about 10 million years Venus suffered another tremendous blow, according to the models.
The most likely answer is that the smallest of the classical planets is simply too close to a very powerful neighbor.
In the animated television show "Invader Zim," Mercury is turned into a prototype giant spaceship by the extinct Martians. Ask your own question! WebWhy don't Mercury and Venus have moons? Any moon with too great a distance from these planets would be in an unstable orbit and be captured by the Sun.
Venus is the second planet from the Sun. Moore Boeck.
Most likely, Venus was slammed early on and gained a moon from the resulting debris. WebA vast number of properties come into play for planets that dont host any moons, but its all primarily due to the sheer force and size of the sun.
Why they named a planet after this guy, I can't imagine.". Everything you need to know about Mercury.
The number of confirmed exoplanets has crossed the 5,000 mark.
Venus has been visited by several spacecraft: Mariner 2, Mariner 5, Mariner The smallest planet in our solar system has a big presence in our collective imagination.
The causes: volcanic and tectonic forces, which could include surface buckling and massive eruptions.
Because Mercury is so close to the Sun and its gravity, it wouldnt be able to hold on to its own moon.
It is unlikely that life as we know itcould survive on Mercury due to solar radiation, and extreme temperatures. A new study finally reveals higher-frequency X-rays and explains why they eluded another mission 30 years ago. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. WebVenus and Mercury are the only planets that do not have moons. Design & Development:
In other words, Venus appears to have completely erased most traces of its early surface. The rover will abrade a rock this week, allowing scientists and engineers to decide whether that target would withstand its powerful drill. Phil Davis & Steve Carney NASAs Parker Solar Probe has taken its first visible light images of the surface of Venus from space. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a 500-million-year period. The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. But newer estimates made with help from computer models paint a different portrait.
If a moon were to lie too far from the planet, the Sun would capture it. This means its far enough away from the Sun to be seen.
WebWhy don't Mercury and Venus have moons? 
Venus does not have any moons.
JPL's lucky peanuts are an unofficial tradition at big mission events. Mercury and Venus are the two innermost planets. Mercury is the smallest planet in our solar system only slightly larger than Earth's Moon. WebMercury and Venus have no moons because of their close proximity to the Sun. Since Mercury and Venus are the two innermost planets, they experience a higher gravitational pull from the sun than the other planets. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system that title belongs to nearby Venus, thanks to its dense atmosphere. Part of the reason is coincidence, but because Venus and Mercury are closer to the Sun than Earth, their Hill-sphere is smaller; there is literally less room for a moon.
WebWhy does Planet Mercury not have moons?
The Next Full Moon is the Wolf Moon, Ice Moon, the Moon after Yule, and the Old Moon.
A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought.
Data received late Sept. 1, 2021, from NASAs Perseverance rover indicate the team has achieved its goal of successfully coring a Mars rock.
For Mercury even more so because it has a relatively low mass and is so close to the Sun. Why Venus doesnt have a moon is a mystery for scientists to solve. Most likely because they are too close to the Sun.
Mercury spins slowly compared to Earth, so one day lasts a long time.
Venus; however, may not have always been moonless. The other planets and dwarf planets in our solar system have at least one moon, but Mars may lose one in 10-50 million years. Because of Mercury's elliptical egg-shaped orbit, and sluggish rotation, the Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. 
WebAnswer: No, Mercury and Venus have no moons.
Every planet in our solar system has moons outside of Mercury and Venus, and this is because they are the closest to the sun. Venus is hotter.
Mercury is the smallest planet in the solar system by size and mass. Mercury is a rocky planet, also known as a terrestrial planet.
It's unlikely that either Mercury or Venus could have moons to begin with.
It's suspected that about 5,000 years ago a comet swept within 23 million miles of the Sun, closer than the innermost planet Mercury.
The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes. Scientists have announced that samples collected by Curiosity are rich in a type of carbon associated with biological processes on Earth.
