What would you bring to mercury?

To survive on Mercury, you would need a spacesuit that can withstand the extreme temperatures during the day and night. Any equipment or technology brought to Mercury would need to be resistant to the intense heat and radiation present on the planet. Additionally, a reliable source of power, such as solar panels, would be necessary due to the lack of atmosphere for wind power.

How many earth years does it take for mercury to make a revolution?

It takes approximately 88 Earth days for the planet Mercury to complete one revolution around the Sun.

How much is cytotec in mercury drugstore?

The price of Cytotec can vary depending on the location and specific store. It is recommended to directly contact your local Mercury Drugstore for the most accurate and up-to-date pricing information.

How many astraunats have travled to planet mercury?

No astronauts have traveled to the planet Mercury. The extreme temperatures and proximity to the sun make it a challenging destination for human exploration. Unmanned spacecraft have been sent to study Mercury, such as NASA's MESSENGER mission.

Which of the facts about the table can scientists use to infer that Mercury has a core made of iron?

Scientists can infer that Mercury has a core made of iron because it has a relatively high density compared to other planets. Additionally, studies of Mercury's magnetic field suggest the presence of an iron core generating the magnetic field. Finally, the data from the MESSENGER spacecraft has provided evidence of a large iron core within Mercury.

How does the sun reflect?

The sun does not reflect as it is a source of light itself. However, objects in space or on Earth can reflect sunlight by bouncing the light off their surfaces, like the Moon reflecting sunlight back to Earth.

Why mercury is less hot than venus?

Although Venus is farther from the sun than Mercury, it is significantly hotter because of its thick atmosphere that traps heat, creating a greenhouse effect. Mercury has a very thin atmosphere that cannot retain heat as effectively, leading to cooler surface temperatures despite being closer to the sun.

Is mercury covered with craters molten iron or oceans?

Mercury is covered with impact craters, similar to Earth's moon. It also has a large iron core, which creates a magnetic field. There is no evidence of oceans on Mercury due to its extreme temperatures.

What is the average daytime and nighttime temperature on Mercury?

The average daytime temperature on Mercury is about 800 degrees Fahrenheit (430 degrees Celsius), while the average nighttime temperature can drop to around -290 degrees Fahrenheit (-180 degrees Celsius) due to the lack of atmosphere to retain heat.

What year did the Messenger orbit around Mercury?

The Messenger spacecraft orbited around Mercury from 2011 to 2015, providing valuable data and insights about the planet's surface, composition, and magnetic field.

Does Mercury have a solid surface or gaseous?

Mercury has a rocky surface, it is the closest planet to the sun in the solar system (however not the hottest). There are only 4 gas giants in our solar system, (Jupiter, Saturn, Neptune and Uranus) how ever astronomers have discovered many other gas planets orbiting other stars in the galaxy. Hope this helps you:)

Why is mercury never seen overhead at midnight in earths sky?

Answer An observer standing on the surface of Mercury and looking up (but not at the sun) would see a black sky because Mercury has no atmosphere to scatter incoming light. food yum

How much money would it be to travel to Mercury and back?

Traveling to Mercury and back would cost billions of dollars, considering spacecraft development, launch, maintenance, and return journey expenses. Currently, there are no commercial trips to Mercury, and only a few spacecraft have been sent there by space agencies at very high costs. It would require significant funding and advanced technology to plan such a mission for human travel.

Is planet Mercury very hot?

No, not always. Even though it's close to the sun, it's long apparent days and nights mean that it's surface temperature can get as low as -170 degrees Celsius. There is no atmosphere on mercury, so the heat can't be held in the same way as on Venus or earth for example. Near the poles, the temperature can drop even lower to around -190 Celsius.

What modifications would be needed for a human to live mercury?

Living on Mercury would be extremely challenging due to its extreme temperatures and lack of atmosphere. Modifications would include advanced thermal protection suits to withstand the intense heat during the day and cold at night, as well as technologies to provide breathable air since Mercury has almost no atmosphere. Additionally, shielding against intense solar radiation would be essential for human survival on the planet.

How much does a bowling ball weigh on Mercury?

A 16 pound bowling ball on Earth would weight approximately 6 pounds on Mercury.

Why is one year on earth 365 days and one year on mercury 88 days?

One year on Earth is 365 days because that's how long it takes for the Earth to orbit around the Sun. One year on Mercury is 88 Earth days because Mercury is closer to the Sun and orbits it much faster than Earth does, causing its year to be shorter.

How hot is mercury's mantle?

The temperature of Mercury's mantle is estimated to be around 1,600°C to 1,700°C (2,912°F to 3,092°F) at its core-mantle boundary. This high temperature is due to the planet's proximity to the Sun and its lack of a substantial atmosphere to regulate heat.

What is closer to the sun Mercury or earth?

Mercury is closer to the earth than the sun is, because the orbit of Mercury is between the sun and the orbit of Earth. However, when Mercury is on the opposite side of the sun from the earth, the sun is closer to the earth than Mercury is.

What makes Mercury's surface dry and almost airless?

Mercury's surface is dry and almost airless because of its close proximity to the Sun, which causes intense solar winds to strip away its atmosphere. Additionally, Mercury's weak gravitational force is not strong enough to hold onto an atmosphere like Earth's. This makes it unable to retain significant amounts of water or air on its surface.

The scarps on Mercury were probably caused by?

The scarps on Mercury were likely caused by the planet's cooling and contraction, resulting in the crust wrinkling and forming cliffs as the surface shrank. This process is similar to how wrinkles form on a drying apple.

How do mercury radius and mass compare with the earths?

Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths.

Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.

How big planets are from smallest to biggest?

Mercury's mass = 0.055 x Earths, Volume = 0.056 x Earths

Mars' mass = 0.1075 x Earths, Volume = 0.151 x Earths

Venus' mass = 0.815 x Earths, Volume = 0.857 x Earths
