On Jan. 2 this year, Earth was 1.471x10^13 cm from the Sun, its closest point to the Sun. The semi-major axis of Earth's orbit around the Sun is 1AU (1.496x10^13 cm. Use this information to determine:
A. The eccentricity of Earth's orbit around the Sun.
B. The difference between the maximum distance between the Earth and Sun, and the minimum distance between the Earth and the Sun. Convert your answer to AU

The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...
A comet in orbit around the sun has an orbital eccentricity 0.4 and semi-major axis 6 AU. What is the comet's furthest distance from the Sun in AU?
An asteroid is in an orbit around the sun whose closest point to the sun has a radius R and whose most distant point has a radius 9R, where R is equal to the radius of the earth's orbit = 1 AU = 1.5 x 10^11 m. 1. What is the asteroid's speed when it is closest to the sun? 2. How does this compare with the earth's orbital speed? 3. What is the period of this orbit, in years?
A comet moves about the Sun in an elliptical orbit, with its closest approach to the Sun being about 0.620 AU and its greatest distance from the sun being 35.5 AU (1 AU = the Earth-Sun distance). If the comet's speed at closest approach is 54.0 km/s, what is its speed when it is farthest from the Sun? (The gravitational force exerted by the Sun on the comet is parallel to the moment arm, so exerts no torque. Therefore, angular...

Activity 3: Kepler's Second Law: Objects in elliptical orbits sweep oul equal areas in'equal times. This implies that the orbital speed of a planet around the sun is not uniform - it moves farthest away (known as APHELION). In this section we will calculate the difference in this fastest at the point closest to the sun (known as the PERIHELION) and slowest at the point speed using Pluto as an example. Pluto's orbit...
A)Some comets are in highly elongated orbits that come very close to the sun at perihelion. The distance from one such comet to the center of the sun is 6.00×10^9m at perihelion and 3.00×10^12m at aphelion. For this comet's orbit, find the semi-major axis. B) In 2017 astronomers discovered a planet orbiting the star HATS-43. The orbit of the planet around HATS-43 has semi-major axis 7.41×109m, eccentricity 0.173, and period 4.39 days. Find the distance between HATS-43 and the planet...

3. Earth's orbit. The Earth, with mass m and angular momentum L, moves around the Sun in arn elliptic orbit of eccentricity e. The equation of trajectory is given by, r=p1+ecoso 1+e where p is the distance of the closest approach to the Sun (perihelion) (a) Find the two components of the velocity as functions ofQie, v,(9) and vo(9). (8 marks) (b) Prove that the angle...
Pluto's orbit around the Sun is highly elliptical compared to the planets in our Solar System. It has a perihelion distance of 29.7 AU and an aphelion distance of 49.5 AU. a) What is the semi-major axis of Pluto's orbit, in AU? b) What is Pluto's orbital period, in Earth years?
What is the angular kinetic energy of the Earth due to its orbit around the sun? In Homework 10, you found the two main angular velocities of the Earth: one due to the Earth's motion around the sun, and one due to its rotation about its own axis. Now let's figure out the energy and momentum associated with that motion. IVO ALV O a ? For the purposes of this problem, treat the Earth as a solid, uniform sphere with...
014 (part 1 of 2) 10.0 points Ever since it was learned that an aster- oid hit the earth 65 million years ago and destroyed most life-forms, including the di- nosaurs, observations of new comets are fol- lowed with great interest! Suppose a new comet is found orbiting the sun as it is pass- ing its point of closest approach at a distance Tmin 0.658 AU (1 AU-semimajor axis (average radius) of the Earth's orbit.) Careful studies determine that its...
