Alpha Centauri A, is also known as the Rigil Kentaurus, this star is one of many star being slightly larger than the Sun. It is a solar like main sequence star with a similar yellowish color, that has a stellar classification to be a spectral type G2V type of star. The TPF has calculated that the orbital parameter of the Alpha Centauri A is about 10 percent more massive than the Sun, with a radius about 22 percent larger. The rotational velocity of this star is 2.7+0.7 km/s, resulting in an estimated

Bone craved to see the Northern Lights. His father had seen it, once upon a winter’s night, and he told Bone what he could to little Bone as his hunting boots thawed on the candle rack. The end of father’s tales had not sated him. When he recounted his wish to the other boys, they laughed at him: “Blind Bone, how will you see the Light?” The boys had beaten him regularly. After they’d left, Bone would get up and weep, but he never held grudges. All he prayed for night after night was a glimpse of

her skin had knitted together with an uneven layer of crusty ice, and when she brushed off the excess, she could not even see a scar, or a blemish, or an imperfection. In fact, her hand was as smooth and cold as a pebble. What was happening? The sun began to fall below the horizon when she walked around the side of the house, looking through the windows until at last she reached the study. She raised herself on tiptoes and peered over the ledge. Dearest Papa. His face looked so haggard under the

the solar system because Newton’s second law of motion states that force equals mass multiplied by acceleration and since the giant planets have more mass, their force increases. Orbits get farther and farther apart as you go away from the sun because the sun gives off gravitational force and as a planet moves farther away, the acceleration increases, increasing the gravitational force. To begin, the giant gas planets are toward the outside of the solar system because they have more mass. The pocket

Galileo Galilei was an astronomer from Italy, Galileo was sent to higher institution to study medicine because his father wanted him to become a doctor. While in higher institution, Galileo discovered that he had a talent for mathematics so he persuaded his father to become a tutor in mathematics and he later became a professor of Mathematics. In the year 1609, Galileo heard about the development of the spyglass which made objects at a far distance seem close. Galileo utilized his arithmetic information

Mankind has long dreamed of touching the stars. Our first taste of expansion came with the moon. It whet humanity’s thirst for the unknown in a whole new way. Now, the biggest step after landing a man on the moon is putting one on Mars. The planet is the closest rock possibly capable of sustaining life and has been a huge subject of debate since the 1960s. Mars captivates the imagination, with many books and movies trying to guess or dream about what life there might be like. But before those dreams

"A caped dark figure moves through the trees into a clearing in the wood. She stops in front of an altar prepared in readiness for her arrival and lights the three votive candles on its surface. When the third candle is lit, torches as if by magick, are lit at the edge of the clearing and more hooded figures enter the circle of light. She turns to look at them, where they are now standing quietly in the circle waiting. She lifts back her hood and loosens the cape, allowing it to fall her feet. In

The constellation Pictor, or The Easel, is a cluster of stars located in the SQ1 quadrant. There are 3 stars in this constellation visible to the unaided human eye, aPic, bPic, and cPic. The shape of the constellation is an easel and palette, although the name itself, Pictor, means painter in Latin. Pictor, or Equuleus Pictoris, is surrounded by the constellations Caelum(the sculptor's tool),Carina(the keel of the argo), Columba(the dove), Dorado(the Swordfish and the Goldfish, Puppis(poop deck of

On the 1st of December, it poured. Curtains of rain were drawn around the bus as it fell heavily, flinging sharp needles in its wake upon the slick ground, before pattering down the sides of the window panes as if they were droplets racing to see who would dissipate first. Outside, ripples were forming on the ground as the bus rolled on by. Some were big circles resembling the spirals of oversized lollipops and some were as small as the size of my palm as they undulated, a pretty sight of monotony

Application of 1st Law to the Orbit aound Sun The closest point to the Sun in a planet's orbit is called perihelion, Rp. The furthest point is called aphelion, Ra. Eccentricity e, of an ellipse is the ratio of distance between the foci to the major-axis of ellipse. The value of ‘e’ for a circle is equal to zero and for an ellipse its value is greater than zero but less than 1. The values of ‘e’ for some planets are listed below. Mercury 0.206 Earth 0.0167 Mars 0.0485 Pluto 0
