By
observing the time between transits
, we know the orbital period. Kepler’s Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known (R3=T2−Mstar/Msun, the radius is in AU and the period is in earth years).
How do you find the orbital period of Jupiter in Earth years?
From Kepler’s 3rd law, P
2
=a
3
, we immediately have P
2
= (2.768)
3
. Solving this for P, we find P = 4.61 years. Jupiter’s orbital period is
11.86 years
. Thus, Jupiter’s period divided by Ceres’ period is P
Jupiter
/P
Ceres
= 11.86/4.61 = 2.57.
How do you determine a planet’s year?
Determine how old you are on the four terrestrial planets (Mercury, Venus, Earth, and Mars). To do this,
divide your age in Earth days by the number of days in a planet’s year
(this information is on the age chart). Your answer is your “new” age. For example, a 20 year old on Earth would be 83 years old on Mercury!
How do you calculate orbits?
The orbit formula,
r = (h
2
/μ)/(1 + e cos θ)
, gives the position of body m
2
in its orbit around m
1
as a function of the true anomaly. For many practical reasons we need to be able to determine the position of m
2
as a function of time.
Is orbital period in years?
A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just
over 365 days
. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
Which is the only planet that can sustain life?
Nonetheless, Earth is the only place in the Universe known to harbor life.
Which planet has the longest year?
Given its distance from the Sun,
Neptune
has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
What is Ceres orbital period in years?
Ceres takes 1,682 Earth days, or
4.6 Earth years
, to make one trip around the Sun. As Ceres orbits the Sun, it completes one rotation every 9 hours, making its day length one of the shortest in the solar system. Ceres’ axis of rotation is tilted just 4 degrees with respect to the plane of its orbit around the Sun.
How do you calculate orbital speed?
- orbital speed = square root (gravitational constant * mass of the attractive body / radius of the orbit)
- Orbital speed Questions:
- Answer: First, we look for default values for the earth, such as mass and its approximate radius.
What is the L quantum number?
The angular momentum quantum number, signified as (l),
describes the general shape or region an electron occupies—its orbital shape
. The value of l depends on the value of the principle quantum number n. The angular momentum quantum number can have positive values of zero to (n − 1).
What unit is orbital period measured in?
The orbital period must be measured in
years
, where 1 year is 365.25 days. This relation has many uses: determining the mass of a planet by looking at its moon(s), studying binary star systems, even determining the mass of the Galaxy!
What is the formula for orbital angular momentum?
mvr = nh/2π
Is Earth the only planet with life?
The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it’s the only one known for sure to have liquid water on its surface. …
Earth is the only planet known to maintain life
.
Which is the closest planet of sun?
Mercury
is the smallest planet in our solar system. It’s a little bigger than Earth’s Moon. It is the closest planet to the Sun, but it’s actually not the hottest.
Which planet is called the morning and evening star?
Mercury
may be seen as an evening “star” near where the sun has set, or as a morning “star” near where the sun will rise. The ancient Greeks called the evening star Hermes and the morning star Apollo, believing them to be different objects. The planet is named for Mercury, the Roman messenger of the gods.
