1,826 Questions

Does the closest planet to the sun have the shortest orbit?

Yes. The closer an object is to the Sun, the shorter the distance it has to travel to get around it.

What is the poem for the order of the planets closest to the sun?

The traditional mnemonic poem for remembering the order of the planets closest to the sun is: "My Very Educated Mother Just Served Us Noodles," where each word represents a planet in order from closest to the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

The nineth closest planet to the sun?

At this moment in time (2010) the last plant is Neptune - the eight planet from the Sun.

What are four more facts about mercury?

  1. Mercury is the smallest planet in our solar system.
  2. It has a very thin atmosphere mostly made up of oxygen, sodium, hydrogen, helium, and potassium.
  3. Mercury has extreme temperature variations between its day and night sides.
  4. It has no moons or rings.

Why were the masses of Mercury and Venus unknown for so long?

The masses of Mercury and Venus were unknown for so long because they do not have any moons orbiting them, which makes it difficult to measure their masses using traditional techniques like gravitational interactions with moons. Instead, scientists had to rely on more indirect methods, such as measuring the orbits of spacecraft exploring these planets or using radar measurements to estimate their masses.

What are the properties of the Jovian planets?

Jovian planets are large gas giants composed mostly of hydrogen and helium. They have thick atmospheres with strong winds, and lack solid surfaces. Jovian planets are typically far from the Sun and have numerous moons and ring systems.

Mercury was first visited by a spacecraft that was the tenth in the series called?

The first spacecraft to visit Mercury was Mariner 10, part of the Mariner program by NASA. It launched in 1973 and made three flybys of Mercury in 1974 and 1975, capturing close-up images of the planet.

Which planet is called messenger of Roman gods?

The planet Mercury is often referred to as the messenger of the Roman gods because in Roman mythology, Mercury was the god of communication, commerce, and travel, which are all associated with the speedy movement of the planet in the sky.

Which lists is the terrestrial planets in order from smallest to largest?

The terrestrial planets in our solar system in order from smallest to largest are Mercury, Mars, Venus, and Earth.

Is mauna loa the smallest planet or the la rgest planet on earth?

Planets are not on Earth. Earth is a planet. And Mauna Loa is not a planet, it is a volcano, the largest volcano on Earth. It is located in Hawaii.

Would a can be crushed due to gravity or atmospheric pressure on mercury?

On Mercury, a can would not be crushed due to gravity because the planet's gravity is too weak. However, the can could be crushed due to the high atmospheric pressure on Mercury, which is about 100 times greater than Earth's atmospheric pressure.

Why does Mercury's days last almost 59 earth days?

Mercury rotates in about 58.65 Earth days. This is called a "sidereal day".

Interestingly there is a big difference between the length of this "day" and

the "solar day"which is about 176 Earth days.

Anyway the reason for the slow rotation is the closeness to the Sun. Tidal

forces are responsible.

Which planet has the longest cycle of day and night of the terrestrial planets?

Mercury has the longest cycle of day and night among the terrestrial planets. A day on Mercury lasts about 176 Earth days, which is longer than a year on Mercury. This is because Mercury rotates very slowly on its axis.

What weights more mercury or Neptune?

Neptune is more massive and therefore weighs more than mercury. Mercury is the smallest planet in our solar system while Neptune is the fourth largest and most massive planet.

A planet that spins once ever 59 earth days?

This planet has a longer day-night cycle than Earth since it takes 59 Earth days for one full rotation. This slow rotation may lead to extreme temperature variations between day and night. The planet's magnetic field and atmospheric conditions could be significantly impacted by this unique spin rate.

How far away from the sun are the dwarf planets?

Dwarf planets are located in the outer solar system, beyond the orbit of Neptune in a region called the Kuiper Belt. This region extends from about 30 astronomical units (AU) to 50 AU from the sun. Pluto, Eris, Haumea, Makemake, and Ceres are examples of dwarf planets located in this region.

And how cold can it be on the side away from sun?

Temperatures on the side of a planet away from the sun can vary depending on the planet's distance from the sun, atmosphere, and other factors. In space, temperatures can drop significantly, sometimes reaching temperatures close to absolute zero (-273 degrees Celsius or -459 degrees Fahrenheit).

What separates the terrestrial and jovian planets?

In our solar system, the asteroid belt lies between the two types of planets. Whether this is due to some overarching influence or merely coincidental cannot be determined at the present time.

Mercury, Venus, Earth, and Mars are small rocky, terrestrial planets.

Jupiter, Saturn, Uranus, and Neptune are larger, predominantly gaseous planets.

Beyond Neptune are many small plutoids and other icy bodies, some of which approach the size of the terrestrial planets. Their gaseous composition, however, means that they would lose much of their mass if they were closer to the Sun.

How long does mercury's storms last?

Mercury's storms can last for several Earth-days to weeks. These storms are driven by the intense heating and cooling cycles on the planet due to its lack of atmosphere.

How many rotation does mercury do in earth day?

Mercury rotates on its axis three times for every two orbits it completes around the Sun. This means that Mercury completes approximately 1.5 rotations in a 24-hour Earth day.

Why is mercury's day equal to 59 earth days?

The gravity of the Sun has slowed the rotation of Mercury, so it takes almost 59 Earth days to spin once on its axis (58.646 days).

At the same time, the relatively brief orbital period (Mercury year) is only 88 days long, even further reducing the apparent motion of the Sun as seen from the planet. A "solar day" (sunrise to sunrise) on Mercury lasts 176 Earth days, or twice as long as its year!

What is the ratio of mercury to earth?

The ratio of Mercury's diameter to Earth's diameter is approximately 0.382.

Why do things that contain mercury need to be placed in a special area?

It needs to be placed in a special place because it can cause extreme brain damage, kidney failure and affects the nervous system. It is the most potent neurotoxin known to man and there is no other chemical that cause so severe brain damage!

Also, it is harmful to the environment. The amount of mercury found in a thermometer is enough to pollute a small lake! I can mutate animals for generations.

Toxicity of mercury has been linked to many different diseases including autism, learning disabilities, Alzheimer's, multiple sclerosis, fibromyalgia, lupus, chronic fatigue syndrome, arthritis, depression and bipolar disorder.

How do i close the rear windows mercury moterey?

To close the rear windows on a Mercury Monterey, locate the window switch on the driver's door panel, typically located near the power window controls. Press the switch in the direction that closes the rear windows until they are fully raised. If the windows do not close, there may be an issue with the power window system that requires further inspection by a professional.
