Can we see Mercury from Earth?

Earth and Mercury, as seen from the north side of the solar system, similarly revolve counterclockwise on their axes. Mercury is viewed in the west after sunset when it is at its greatest eastern elongation, and in the east before sunrise when it is at its greatest western elongation.

They both have very small orbits around the Sun (86 million miles or 133 million km), but because they are so close to the Sun they each receive a year worth of sunlight in just four months. Thus, they are always daylighted even if the rest of the planet is not. They also both have one face toward the Sun at all times, which means that they are always hot enough for water to be liquid. However, because they are so far away from the rest of the planets, there is no effect on their climate due to other bodies' activity.

Earth's moon has a major influence on earth's environment through the process of meteorology. When the moon is out, clouds don't rise from the oceans nor do storms develop over land. This is because air can only move along horizontal surfaces - clouds form when moisture in the air condenses into droplets large enough to fall as rain or snow. Clouds reflect light from the sun back into space, while darkness falls quickly over the world when they cover the sky. During a storm, the presence of the moon can prevent it from becoming severe.

Does Mercury revolve?

Mercury rotates on its axis slowly, completing one revolution every 59 Earth days. Mercury's axis of rotation is just 2 degrees inclined in relation to the plane of its orbit around the Sun. That means it rotates nearly exactly upright and, as a result, does not have seasons like many other planets. However, because of the precession of equinoxes, over time Mercury's axis will point toward the east-west direction from its current position near the Sun.

Like the Moon, Mercury has a large impact crater named Copernicus on its surface. The 108-mile-wide (174 km) basin is almost half as big as the state of Delaware. It was created by a massive explosion or volcanic eruption about 1200 years ago!

Although most planets in our solar system rotate on an axis, only three (Earth, Mars, and Jupiter) are classified as "icy" (made of ice). The other four (Venus, Uranus, Neptune, and Pluto) are composed of gas and rock.

All five planets except Mercury can be seen with the naked eye from the Earth provided they are visible during twilight or night. Mercury is always invisible to the human eye because it goes directly from darkness to daylight as viewed from our planet. The planet emerges from behind the Sun each morning and disappears into it each evening.

Astronomers use telescopes to see things that are invisible to the naked eye.

Is Mercury currently visible at sunrise or sunset or both?

Mercury is our solar system's nearest planet to the Sun. It is only seen in the early morning, soon after dawn, or after sunset since it is so near to the sun. In fact, ancient Greek astronomers once thought Mercury was two distinct objects. They called the bright object "Phoebus" after its Roman name.

Today, most people see Mercury when it is high in the sky and just before dawn or after dusk. You can also see it in a clear night with a reasonably dark sky. It goes around the Earth every 88 days at an average distance of 40 million km (25 million miles). That makes it take about four months to orbit the Sun.

It is always visible as a faint point of light in the evening twilight. With a small telescope you can see features on its surface such as polar ice caps and volcanoes. But because it is so close to the Sun, Mercury has very little atmosphere and no water or other resources to support life as we know it. It is entirely covered by a thick layer of carbon dioxide gas.

The best times to observe Mercury are: between 4 and 8 am, when it's highest in the sky; and after 6 pm, when it's low on the horizon. Note that these are local times, so you will need to adjust them for your location.

Is the planet Mercury an active plate tectonic planet?

Mercury has been discovered to have tectonic activity. Images from NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) satellite show geologic characteristics that suggest Mercury is still shrinking today, joining Earth as a tectonically active planet in our Solar System.

Tectonics is the study of plates and their movement on planets or within stars. On Earth, tectonics results in mountain building, fault formation, and other significant changes to the surface. On other planets or moons where there are no strong forces keeping parts of the body together, gravity becomes important. The force of gravity causes plates of rock or ice to slip over one another, creating a drift zone where rocks fall toward the middle of the planet or moon.

On Mercury, the drift zone occurs near the center of the planet and seems to be spreading out from there. This may be because the core of Mercury is shrinking, causing the inner part of the planet to drift away from the outer part. Or it could be due to dynamic effects caused by small variations in mass across the face of the planet. Either way, this is evidence that something is happening beneath the surface that is causing parts of Mercury to move around relative to each other.

It has also been suggested that tidal forces acting between the Sun and Mercury might be responsible for some aspects of Mercury's tectonics.
