What year was the meteor crater made in AZ?
The Meteor Crater in Arizona was formed around 50,000 years ago when a large meteorite struck the Earth. It is one of the best-preserved impact craters on Earth and is estimated to be around 50,000 years old.
What best represents the relative periods of rotation of Mercury Venus Earth and Mars?
Mercury has the shortest rotation period, taking about 59 Earth days to complete one rotation. Venus has an unusual rotation period of about 243 Earth days, which is longer than its orbital period around the Sun. Earth rotates once every 24 hours, while Mars has a rotation period of approximately 24.6 hours. Thus, the sequence from shortest to longest rotation periods is Mercury, Earth, Mars, and then Venus.
Does Jupiter have impact craters?
Yes, Jupiter does have impact craters; however, they are not as prominent as those found on solid bodies like the Moon or Mars. Jupiter's strong gravitational pull and turbulent atmosphere cause impacts to be quickly obscured or erased over time. The Galileo spacecraft detected some impact scars on Jupiter's moons, indicating that impacts do occur in the Jovian system.
How many days does it take mercury to rotate?
It takes about 58.6 Earth days.
What is the composite of mercury?
Mercury is classed as a rocky body like the Earth. Its core (about 1800 kilometers in radius) is likely almost all iron. The mantle (about 600 kilometers thick) contains mostly silicates, as does the relatively thin crust.Overall, the best estimates are that 70% of the planet's mass is iron and the other 30% is silicate material.
What is planet Mercury's best known feature?
== == That would be the craters on its surface, particularly the Caloris Basin, a 1500 km impact crater.
Why is Mercury harder to see from earth?
mercury is hard to see from the earth because it is so close to the sun. it is best to view mercury either at sun rise or sun set.
What statement best explains why the moon has more craters than earth?
The moon has more craters than Earth primarily because it lacks a significant atmosphere, which means there is no weathering or erosion to diminish the visibility of impact sites. Additionally, the moon has no active geological processes, like plate tectonics or volcanic activity, that could reshape its surface and erase craters over time. In contrast, Earth's atmosphere, water, and geological activity continuously alter its surface, leading to fewer visible craters.
Which planet is less than half the diameter of the earth and look like your own moon?
Mercury best answers this question, as it is the only planet less than half the size of Earth (whereas Mars is about 2/3rds the size of Earth and Venus about 3/4ths) and has almost no atmosphere (like the moon) (whereas Mars has much more atmosphere than the Moon or Mercury, though quite thin compared with the other planets, and Venus has a very thick atmosphere even compared with Earth); this lack of atmosphere lets craters accumulate on Mercury's surface, much like our Moon's; on Venus, Earth and Mars, our atmospheres are thick enough that fewer asteroids are able to survive descent to create craters in the first place and even when asteroids and other bodies in space are able to impact the surfaces of Venus, Earth or Mars, weather will, over time, erode away those impact craters (even on Mars; its atmosphere is sufficiently thick to give it very impressive dust storms which can erode raised crater rims and fill crater basins). However, Mercury has a number of significant differences than the moon, chiefly that it is much denser (in fact, it is denser than earth and all other planets) with a large iron core (the moon has very little iron by comparison) ... in fact, Mercury's iron core is estimated to be larger than Earth's (but has much less stuff outside the core, so the planet overall is significantly smaller than Earth). The moon has no magnetic field of its own, but Mercury does (although only about 1% as strong as earth's). Because it is much closer to the sun, Mercury is much warmer than our Moon.
When is the best time to observe craters?
After they hit the ground.

Are there bottomless craters on the moon?
Yes there are craters, and yes some of them are very deep. All craters, however, do in fact have a bottom. A bottomless crater would actually be best described as a "hole," and there are no holes through the Moon.
Which state is the barringer meteor crater located?
the barringer crater is located in Arizona
How can we purify mercury?
The best method to purify mercury is distillation.
Name all the planets closest to the sun?
There is only one planet 'closest' to the sun. To the best of current knowledge, it is the planet Mercury.
From Earth when can you see mercury?
at nightnime Depending on Mercury's position, the longest you can see it, is about 1 hour after sunset or 1 hour before sunrise, and when Mercury is at a right angle from the sun as viewed from Earth. This is when Mercury appears to be farthest from the sun. As Mercury orbits the sun, it appears to be closer to the sun, and will be visible for a shorter amount of time. You will need to have an unobstructed view of the horizon.
Is the Mercury is the best conductor of heat?
It's not, there are materials that are better, like diamond.
