What is the difference between asteroids and comets? Comets are visible without a telescope. Asteroids are mostly rock and rock pieces, comets are composed of ice, gases, and dust. List seven years that Halley's comet has come by the earth.

All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. ... They are highly eccentric or "squashed." They look more like thin ellipses than circles. Satellites that orbit Earth, including the moon, do not always stay the same distance from Earth.

Aneroid barometer and mercury barometer are such two types. The main difference between aneroid and mercury barometer is that aneroid barometer measures the atmospheric pressure using the expansion of a metal whereas mercury barometer measures the atmospheric pressure by adjusting the height of mercury inside a tube.

The pahoehoe flow has a comparatively smooth or "ropy" surface. ... The surface of the aa flow consists of free chunks of very angular pieces of lava. This difference in form reflects flow dynamics.

When at "perihelion" (the orbital point where a planet is closest to the Sun), Mercury is about 46.0 million km from the Sun and at "aphelion" (the orbital point farthest from the Sun), it is at a distance of 69.8 million km.

Apoapsis and periapsis are the generic terms for describing the farthest and closest points of an orbit to the body being orbited. Ge comes from the Greek for Earth, so apogee and perigee are indeed simply other names for the apoapsis and periapsis of an item orbiting the Earth.

Generally, planets closer to the sun are rocky (Mercy, Venus, Earth, Mars), whereas planets further away are made of gasses (Juptier, Venus, Uranus, Neptune) because as the planets formed, the planets closer to the sun had their gasses were stripped away due to the heat of the sun, whereas planets slightly further away ...

The homosphere is the portion of the atmosphere close to the earth where winds mix up the gasses into a more or less homogeneous (the same throughout) mass. ... The heterosphere is the portion of the atmosphere above this, further away from the earth, where different conditions cause the gasses to separate out into layers.

The Northern Hemisphere refers to the half of the planet that is north of the equator, while the Southern Hemisphere is all of the planet south of the equator. ... The North Pole, of course, is in the Northern Hemisphere, while the South Pole is at the most southerly part of the Southern Hemisphere.

As nouns the difference between latitude and altitude is that latitude is (geography|astronomy) the angular distance north or south from a planet's equator, measured along the meridian of that particular point while altitude is the height measured from sea level up to any given point.

The key difference is that the Moon is further away from the Earth during an Annular as compared to a Total Eclipse. This gives the appearance of the Moon being smaller in the sky, and it no longer completely covers the Sun. Instead, a 'ring of fire' remains – the Sun still emits direct light.
