The Discovery of Neptune Neptune was discovered in September 1845. It was discovered by means of mathematics before being seen through a telescope. It began in 1843 when John Adams‚ a young English astronomer and mathematician‚ began working to find thew location of the unknown planet. Adams predicted the planned would be about 1.6 billion kilometres farther from the sun then Uranus. That’s when he completed his work in September 1845. Also Urbain Leverriar‚ unknown to Adams‚ began working

1) Why does the Earth have seasons? Describe the relationship of the Earth and Sun in each of our four seasons. Contrary to what most people believe‚ seasons on Earth are not caused by the distance of our planet in relation to the Sun. This is a common misconception due to the Earth’s elliptical orbit around the Sun‚ which means there are times that the Earth is closer to the Sun‚ and times when it is farther away. If the Earth’s proximity to the Sun was the cause of our seasons‚ then they would

Am I the only who thinks that the moon is following me back? That’s what I thought when I was a little kid. Weird isn’t? Well‚ that’s what I believe in. Believing that I’m completely different among children’s at my age that time‚ up to this point. I always have that kind of feeling. Eagerness to do the impossible things. Possibly all crazy stuffs actually. If I remember it correctly I loved experimenting things such as insects when I was a kid. Capturing ants and spiders then eventually I’ll devour

The Lagrange point phenomenon exists in any system wherein the gravitational fields of two large bodies interact to create five “sweet spots”‚ within which lies the exact centripetal force necessary for a smaller object to remain in a constant orbit with the larger objects. There are five Lagrange points within the Sun-Earth orbit‚ as well as five Lagrange points within the Earth-Moon orbit. These points will vary according to the mass of the two larger objects‚ as well as the distance between

Calculation: Use Kepler’s Third Law (M=(4π^2 r^3)/(GP^2 )) to calculate the mass of “Object X” from the orbit of its moon—whose orbital radius (r) is 64‚780 kilometers and whose orbital period (P) is 38.200 days—and knowing that the gravitational constant G= 6.673×〖10〗^(-11) m^3 〖kg〗^(-1) s^(-2)(where m= meters‚ kg= kilograms‚ and s=seconds). Express the answer in units of Earth Mass (M_Earth)‚ knowing that M_Earth= 5.980×〖10〗^24 kg. (Hint: first express r and p in standard units: meters and seconds

By looking at both graphs we can see that from □(→┬AB ) the spaceship is accelerating from 0 to 0.95c until it reaches the Asteroid belt. The asteroid belt is located at 1.7AU far from earth ‚ Then 95% of the speed of light can be written as 2.85X〖10〗^8 m/s and one AU equals 1.496×〖10〗^11 mt‚ to calculate how much time the spaceship takes to reach B we have (1.7(1.496x〖10〗^11 m))/(1/2((2.85×〖10〗^8 m)/s))=~1778s or approximately 30 minutes. Whereas from C to D the spaceship desaccelerates at a

Astronomy 104 Chapter 3 1. Scientific thinking is our ability to use our prior knowledge and use the knowledge in finding answers to new knowledge. This differs from our everyday thinking because we probably wouldn’t be trying to acquire new information which scientific thinking we always are. 2. In early history astronomy was heavily tied to religion and so usually the priest were astronomers using the star patterns to interpret what the god were saying. Also they based the star patterns of there

To be considered a planet of our solar system you need many different aspects which may seem effortless to understand although there is endless information which is new to scientists everyday. Pluto has some but certainly not all the qualities as it was found orbiting the Kuiper belt which is beyond the orbit of Neptune‚ the current furthest planet from the sun. Pluto has been one of the 9 planets in the past‚ but now that scientists have higher tech machines and programmes to allow them to explore

History of Long-Term Comets Have you ever wondered who and how things were discovered? Who named Mars‚ how the names for constellations for created‚ or how long-term or short-term comets were named and discovered? Long-Term comets are comets that have an orbital period greater than 200 years and are 50‚000-70‚000 AU (astronomical units) from the sun. In this paper‚ I will tell you briefly about how long-term comets are named and seen‚ and about two major long-term comets‚ Comet West and Comet Kohoutek
