According to the solar nebula theory, why is the Earth’s orbit nearly in the plane of the Sun’s equator?
A planet with 20 times the earth's mass and 3 times its radius exists. It orbits a star with twice the sun's mass with a circular orbit of radius 18 AU where 1 AU is the earth sun distance.1. What is the period of the planet's orbit in years? 2. Suppose something weighs 1600 books (books is a unit of mass) on that planet, what is it weight on earth in books?
•• The Sun, with Earth in tow, orbits about the center of the MilkyWay galaxy at a speed of 137 miles per second, completing one revolution every 240 million years. (a) Find the angular speed of theSun relative to the center of the Milky Way. (b) Find the distancefrom the Sun to the center of the Milky Way
What is an orbital acceleration on an object? Explain it by giving an example.
While the Earth spins around its axis and orbits around the sun, then suppose we remove the sun from its location, will Earth continue to spin around its axis and orbits around the point where the sun used to be? Why or why not?
A planet orbits a star in an elliptical orbit. At its farthest point its center is 200,000,000 km from the center of star. At its closest point its center is 100,000,000 km from the center of of the star. How does the orbital speed of the planet when it is at its closest point compare to the orbital speed of the planet when it is at its farthest point? a-The speeds are the same. b-it goes at less than half the speed at the closest point. c-It goes slower at the closest point, but faster than half as fast. d-It goes twice as fast at the closest point. e-It goes faster at the closest point, but less than twice as fast. f-It goes half as fast at the closest point. g-It goes more than twice as fast at the closest point.
You are an astronomer on planet Tirth, which orbits a distant star. It has recently been accepted that Tirth is spherical in shape, though no one knows its size. One day, you learn that on the equinox your sun is directly overhead in the city of Tyene, located 450 kilometers due north of you. On the equinox, you go outside in Alectown and observe that the altitude of your sun is 85 ∘∘. What is the circumference of Tirth? Express your answer in kilometers to two significant figures.
Using Kepler’s Third Law (r3 = MT2 where M is the mass of the central star) find the orbital radius in astronomical units of this planet. M = 1.5 times the mass of the sun. Remember to convert days to years using 365.25 as the length of a year in days. Key Points to know: - The semimajor axis of the planet in AU is r = 0.0379 AU - The circumference of the orbit is l = 3.562 x 10^10 m - The orbital velocity in m/s is v = 1.874 x 10^5 m/s Questions that need to be answered: - With that orbital velocity, the radius of the orbit in meters, find the centripetal acceleration of our exoplanet: - Knowing the acceleration that our planet experiences, calculate the force that the host star exerts on the planet: - Knowing the force on the planet, the orbital radius, and the mass of the parent star, use the equation for gravitational force to find the mass of our planet (m2). (To get m1 in kg multiply the mass of the star in solar masses by 1.98 x 1030).
In a certain binary-star system, each star has the same mass as our Sun, and they revolve about their center of mass. The distance between them is the same as the distance between Earth and the Sun.What is their period of revolution in years?

earth orbit is about 147.1 million kilometers at perihelion and about 152.1 million killometers at aphelion determine an equation relating earths orbit around the sun in millions of killometers with the center of the horizontal ellipse at the origin.
when our sun (whose current radius is about 700,000 km and which rotates once in roughly 2.6Ms) runs out of fuel, it will eventually become a white dwarf stare with about the same radius as the earth (6380km). Estimate the suns's rotational period when it is that size.
