    This might sound crazy for many, I moved to the UK in 2014 since than I have been noticing differences in the size of the sun and the distance the sun stays from the earth. In the winter the sun appears to be bigger and closer to the earth, while in the summer the Sun seams to be smaller in size and further out in the sky. Does anyone have a explanation for this?

  • Does our sun have a name?

    Best answer: The official name, in English, of our star is Sun (with a capital S). The word "sun" (small s) is a simile: a word used to describe things that are similar. Other stars that have planets are often called suns (small s), but in astronomy, we try to avoid the simile unless it is quite clear. Our Sun's... show more
    Best answer: The official name, in English, of our star is Sun (with a capital S). The word "sun" (small s) is a simile: a word used to describe things that are similar. Other stars that have planets are often called suns (small s), but in astronomy, we try to avoid the simile unless it is quite clear.
    Our Sun's name, in Latin, is Sol. That is why we have the adjective solar, in English.
    The Solar system (the system of planets around "Sol") is OUR planetary system. Other planetary planets (around other stars) are not solar systems (they are planetary systems or systems of planets).
    The name of our Sun in Greek is Helios. That is why we talk of the heliographic system (the system describing the Sun as the centre).

    The official name, in English, for our natural satellite is Moon (capital M). The word moon (small m) can be used as a simile for other objects that are similar. For example, the moons of Jupiter. However, in astronomy, the official word for these things is "satellite".
    Moon's name in Latin is Luna; we have the adjective lunar, in English.

    Our Galaxy's official name in English is (was) Galaxy - with a capital G. Other galaxies are given names that depend on the direction in which we see them from Earth (the Andromeda galaxy appears to be in the constellation called Andromeda), or on the shape of the galaxy (the Sombrero galaxy looks like... a sombrero), or the number it has in some official list (for example NGC-224, for the 224th galaxy listed in the New General Catalogue).
    The Milky Way is a band of stars that makes up a part of our Galaxy. Calling our Galaxy the Milky Way galaxy (with or without a big G) is not wrong, but it is redundant (the word galaxy comes from a Greek word meaning "milky").

    The problems started when an American astronomy magazine asked authors to use lower-case letters for the proper names of the Sun and the Moon, giving people the false impression that these things had no names.

  • Am I seeing mars in the sky?

    It's currently 03:34 AM in Scotland, and the sun is starting to rise. I had a look outside since it was very early, and over to my right I saw 1 single star which looked orange. When I first saw it I thought it was just a plane, but I looked out again 5 minutes later and it was in the exact same spot. Is this mars? show more

  • Why isn't Pluto considered a planet?

    Best answer: Because it doesn't meet the definition.

    It always looked a bit odd compared to the others but for years it was the only one like it we knew. So it was classed as a planet. Then more started to be discovered further out so it was realised Pluto is just the closest of the Kuiper Belt objects. Now either all those are planets as well, or they're not and neither is Pluto. So the International Astronomical Union came up with a definition of a planet.

    1. It orbits the Sun. Pluto does that.
    2. It is in hydrostatic equilibrium - that is, it's big enough for its own gravity to have squashed it into as nearly a sphere as possible. That's true too.
    3. It has "cleared its neighbourhood" - that is, it is the most dominant thing gravitationally in its orbit. Pluto fails this test because the most dominant thing in its orbit is Neptune. It crosses the orbit of Neptune and is in 3:2 orbital resonance with it - it orbits the Sun exactly twice for every three times Neptune orbits. This is the influence of Neptune's gravity.

    So Pluto is not a planet. But it fits the first two parts so it's a dwarf planet.

  • Hypothetical question, and probably a stupid one. Would this work to solve the climate change dilemma?

    Best answer: Would likely take more energy than we could produce mining/drilling the whole planet...

    Not to mention the problem of seasons/day length changing and that alone causing mass plant die-off... among many other things.

    "...657 new islands discovered by satellite imagery. Of course, they are immediately declared threatened by sea level rise
    Anthony Watts / April 21, 2011

    Chandeleur Islands - Image: Univ of Montana

    From LiveScience.com

    Here’s something you don’t see every day — hundreds of new islands have been discovered around the world.

    The Earth has 657 more barrier islands than previously thought, according to a new global survey by researchers from Duke University and Meredith College in Raleigh, N.C.

    The researchers identified a total of 2,149 barrier islands worldwide using satellite images, topographical maps and navigational charts. The new total is significantly higher than the 1,492 islands identified in a 2001 survey conducted without the aid of publicly available satellite imagery...."

    So I was at a bonfire party in rural indiana last weekend (June 16) with a good 10-20 of people. Once it became dark, we all pretty much quit staring at the fire and started gazing up at the stars. Around 1 am, while listening to music on a phone via the stereo, a spectacularly bright comet went streaking directly over us. It burned a bright magnificent green, causing the trail of smoke to be clearly visible going across the entire sky. In the 2 or 3 sec this took place, the radio went completely static, quickly returning to normal once it had gone! So what element in its composition would cause this interruption? Why would the stereo even go static considering the music was coming from a phone via aux cord and not a tuned in radio signal? Thanks for the help!

  • A scientist suggested that NASA build a unmanned space station on the Mercury and locate this station in a crater at its north pole.?

    Best answer: 1- Going to Mercury requires almost as much energy as going to Jupiter (unlike going to Jupiter, where you speed out towards the outside of the solar system, going to Mercury requires losing a lot of energy to fall to the lower orbit; in space, accelerating and decelerating is the same, it is just a matter of... show more
    Best answer: 1- Going to Mercury requires almost as much energy as going to Jupiter (unlike going to Jupiter, where you speed out towards the outside of the solar system, going to Mercury requires losing a lot of energy to fall to the lower orbit; in space, accelerating and decelerating is the same, it is just a matter of direction)
    2- Reaching Mercury's pole means realigning the orbit from a equatorial to a polar orbit; that is also a lot of energy
    3- While in orbit (and while approaching) any ship is exposed to a between 5 to 10 times as much solar energy as we get on Earth. While this would work great for solar panels, this means the ship (and crew) would tend to be cooked quite a lot
    4- At the pole, due to the lack of atmosphere, in the shade, the temperature is around 110 K. That is -163 C. Or -262 F if you are still stuck with the antiquated system of units.
    5- The absence of atmosphere means that landing on Mercury has to be done purely with retro rocket, as opposed to parachute with ablative of refractory heat shields like on space capsule or shuttle. This means you need about as much fuel to land from orbit as is required to lift off from the surface
