Test 1 (part 2)
Question Answer
A planet whose distance from the Sun is 3 A.U. would have an orbital period of how many Earth-years? √27
The place in a planet’s orbit that is closest to the Sun is called perihelion.

How do you find the orbital period of a planet using Au?

If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years then Kepler’s Third Law says P2 = a3. where P is in Earth years a is in AU and M is the mass of the central object in units of the mass of the Sun.

How do you calculate orbital period?

How is AU distance calculated?

For general reference we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km). It’s approximately 8 light-minutes. More exactly one astronomical unit (AU) = 92 955 807 miles (149 597 871 km).

What is orbital distance?

In physics you can use orbital distance to determine how long it takes for an object to revolve around another one. For example you can calculate how long it takes Mars to travel around the Sun given its distance from the Sun in astronomical units.

Saturn 9.539 AU 886.7 million miles 1 427.0 million km

What is the orbital distance of Venus?

108 million km
Venus orbits the Sun at a mean distance of 108 million km (67 million miles) which is about 0.7 times Earth’s distance from the Sun. It has the least eccentric orbit of any planet with a deviation from a perfect circle of only about 1 part in 150.Oct 28 2021

How do planets orbit around the Sun?

The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.

What is an orbit for Class 3?

An orbit is a regular repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural like Earth (or) the moon (or) like some other planets also.

What is the orbital period of each planet?

The Days (And Years) Of Our Lives
Planet Rotation Period Revolution Period
Mercury 58.6 days 87.97 days
Venus 243 days 224.7 days
Earth 0.99 days 365.26 days
Mars 1.03 days 1.88 years

What is the orbital period of the following planets?

Planetary Fact Sheet – Metric
Perihelion (106 km) 46.0 1352.6
Aphelion (106 km) 69.8 1514.5
Orbital Period (days) 88.0 10 747
Orbital Velocity (km/s) 47.4 9.7

How do we measure the distance between planets and the sun?

Distance between earth and sun a = around 150 million km defined as one Astronomical Unit (AU). Radius of the Sun Rsun = around 700 000 km. Orbital speed of Earth v = around 30 km/s.

What is the relationship between distance from the Sun and orbital period?

The further away from the Sun it is the slower the planet’s orbital speed and the longer its path. Both of those factors result in taking longer to make one complete orbit and a planet having a longer year.

What is the relationship between the distance from the Sun and the orbital period quizlet?

A planet’s orbital period is the length of time necessary to complete one revolution around its star. According to Kepler’s third law of planetary motion the square of a planet’s orbital period is directly proportional to the cube of its average distance from the sun.

Why are AU and Ly used to determine the distance between planets and the Sun in the solar system?

Astronomical units are just a useful way to think about the solar system relative to the distance from Earth to the Sun because it’s easy to use. … When you use AU it is easier to understand the relative distances and that Saturn is about ten times farther from the sun.

How many AU is Venus from the Sun?

0.7 AU

The true average distance from the Sun to Venus is about 108 000 000 km (67 000 000 miles) or 0.7 AU.

How many AU is Mercury from the Sun?

0.387 Astronomical Units

Mercury has no moons and it is the planet closest to the Sun. The planet’s distance from the Sun is 0.387 Astronomical Units (1 A.U. = 93 000 000 miles) or about 36 million miles away.

How do you find Au in physics?

What is Jupiter’s AU from the Sun?

5.2 Astronomical Units

Jupiter orbits about 484 million miles (778 million kilometers) or 5.2 Astronomical Units (AU) from our Sun (Earth is one AU from the Sun).

What planet is 778600000 distance from the Sun?

What’s Pluto’s distance from the Sun?

39.5 astronomical units
On average Pluto is a distance of 39.5 astronomical units or AU from the sun. That is almost 40 times farther from the sun than Earth is. Because of its elliptical orbit Pluto is not the same distance from the sun all the time. Pluto’s closest point to the sun is 29.7 AU.Aug 4 2015

What is the transition period and orbit period of Venus?

They occur in a pattern that generally repeats every 243 years with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities.

What is the orbital period of Jupiter?

12 years

What is the orbital period of Mars?

687 days

Why are we orbiting the sun?

Anyway the basic reason why the planets revolve around or orbit the Sun is that the gravity of the Sun keeps them in their orbits. Just as the Moon orbits the Earth because of the pull of Earth’s gravity the Earth orbits the Sun because of the pull of the Sun’s gravity.

What is the orbital motion of the galaxy?

The planets orbit the Sun roughly in the same plane. The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane. The Sun appears to move up-and-down and in-and-out with respect to the rest of the galaxy as it revolves around the Milky Way.

How do planets rotate?

The planets all revolve around the sun in the same direction and in virtually the same plane. In addition they all rotate in the same general direction with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets’ formation.

What is the orbit of the planet?

365 days

What is an orbital answer?

In chemistry and quantum mechanics an orbital is a mathematical function that describes the wave-like behavior of an electron electron pair or (less commonly) nucleons. An orbital can contain two electrons with paired spins and is often associated with a specific region of an atom. …

What is Earth’s orbit kids?

The Earth’s orbit makes a circle around the sun. At the same time the Earth orbits around the sun it also spins. In science we call that rotating on its axis. Since the Earth orbits the sun AND rotates on its axis at the same time we experience seasons day and night and changing shadows throughout the day.

Which planet has the shortest orbital period?


Mercury is an extreme planet in several respects. Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.

Which planet takes 84 years to orbit the sun?
