Have you ever heard that the Solar System is compared to a football field? When you look at the size of the Sun compared to Jupiter on the football field, the sun is the size of a U.S. dime, while Jupiter is only the thickness of a U.S. quarter. How big is the Sun in terms...
The Andromeda galaxy, pictured here, is just one of many in the known universe. Tony Rowell / Getty Images When you look up at the night sky, especially during the summer, you'll see a faint band of stars spread across the entire middle of the sky. The sun is just one of about ...
The source of the light on earth is the sun. Sun is one of the stars made up of hydrogen and helium molecules. The nuclear fusion reaction between hydrogen and helium releases an enormous amount of energy.Answer and Explanation: The width of the sun is 1.3927 million km. D...
What do Mars and Jupiter have to do with it, and how do their orbits affect the main belt? What about the Kuiper belt and the Oort cloud -- are they any different from the main one? Are there other asteroid belts in other solar systems like ours, or is the main belt unique? Keep...
It pushes outwards. Rather than atoms holding up a star against gravity, it's now the radiation from the nuclear fusion you began. A low-mass star like a Red Dwarf is many times larger than Jupiter, while a star as massive as the Sun is significantly larger still. ...
Earth’s orbit would not be changed if Jupiter were a small star (the mass would be 100 current Jupiter masses). Jupiter and the Sun would orbit each other around a barrycenter (a common center of mass) this would be about one-half of an AU (AU=earth-sun distance...
Estimating distancesin astronomy is challenging. Think of how hard it is to estimate the distance of someone pointing a flashlight at you on a dark night. Galaxies come in a very wide range of sizes and masses. Measuring a galaxy’s brightness or apparent size isnot a good guideto its dis...
As digital technology has advanced, so have the capability of these synths. TheRoland JUPITER-XandJUPITER-Xmuse a new synth engine that combines PCM wave sample-based synthesis with Roland's VA (Virtual Analog) synthesis to create both realistic synthesized instrument sounds and a world of classi...
This time the insistence that the check is in the mail was probably true; but it would not be perceived as such by the party awaiting the envelope that never arrived. One can only imagine how many apologies went without receipt; and worse still, how many love letters never made it into ...
(such as Earth and Mars) or cool gases (such as Jupiter and Saturn). By understanding how the Sun works, astronomers can gain a deeper insight into how all stars work. Conversely, if they study many other stars throughout their lives, it's possible to figure out the future of our own...
