Julian Century Solution

STEP 0: Pre-Calculation Summary

Formula Used

Julian Century = (Julian Day-Julian Day Reference)/Reference Time
JC = (JD-JD_ref)/t_ref
This formula uses 4 Variables

Variables Used

Julian Century - (Measured in Second) - Julian Century is used to simplify calculations of the positions of celestial objects in the sky, such as the sun, moon, and planets.
Julian Day - (Measured in Second) - Julian Day refers to a system of timekeeping that is commonly used to synchronize various operations and events.
Julian Day Reference - (Measured in Second) - The Julian day reference is a system used to represent dates and times in a standardized format.
Reference Time - Reference Time is the time period for which statistical results are collected or calculated and to which, as a result, these values refer.

STEP 1: Convert Input(s) to Base Unit

Julian Day: 427 Day --> 36892800 Second (Check conversion here)
Julian Day Reference: 7 Day --> 604800 Second (Check conversion here)
Reference Time: 1.4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

JC = (JD-JD_ref)/t_ref --> (36892800-604800)/1.4

Evaluating ... ...

JC = 25920000

STEP 3: Convert Result to Output's Unit

25920000 Second -->300 Day (Check conversion here)

FINAL ANSWER

300 Day <-- Julian Century

(Calculation completed in 00.004 seconds)

Position Vector

Go Position Vector = (Major Axis*(1-Eccentricity^2))/(1+Eccentricity*cos(True Anomaly))

Kepler's First Law

Go Eccentricity = sqrt((Semi Major Axis^2-Semi Minor Axis^2))/Semi Major Axis

Mean Anomaly

Go Mean Anomaly = Eccentric Anomaly-Eccentricity*sin(Eccentric Anomaly)

True Anomaly

Go True Anomaly = Mean Anomaly+(2*Eccentricity*sin(Mean Anomaly))

Universal Time

Go Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600))

Reference Time in Julian Centuries

Go Reference Time = (Julian Day-Julian Day Reference)/Julian Century

Julian Century

Go Julian Century = (Julian Day-Julian Day Reference)/Reference Time

Julian Day

Go Julian Day = (Reference Time*Julian Century)+Julian Day Reference

Nominal Mean Motion

Go Nominal Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)

Mean Motion of Satellite

Go Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)

Local Sidereal Time

Go Local Sidereal Time = Greenwich Sidereal Time+East Longitude

Kepler's Third Law

Go Semi Major Axis = ([GM.Earth]/Mean Motion^2)^(1/3)

Range Vector

Go Range Vector = Satellite Radius Vector-[Earth-R]

Orbital Period of Satellite in Minutes

Go Orbital Period in Minutes = 2*pi/Mean Motion

Anomalistic Period

Go Anomalistic Period = (2*pi)/Mean Motion

Universal Time Degree

Go Universal Time Degree = (Universal Time*360)

Julian Century Formula

Julian Century = (Julian Day-Julian Day Reference)/Reference Time
JC = (JD-JD_ref)/t_ref

What is UTC time zone?

The World's Time Standard, Coordinated Universal Time (UTC) is the basis for civil time today. This 24-hour time standard is kept using highly precise atomic clocks combined with the Earth's rotation.

How to Calculate Julian Century?

Julian Century calculator uses Julian Century = (Julian Day-Julian Day Reference)/Reference Time to calculate the Julian Century, The Julian century formula is defined as an interval of 36,525 days mean solar days. The time interval is reckoned from a reference time of January 0.5, 1900, which corresponds to 2,415,020 Julian days. Julian Century is denoted by JC symbol.

How to calculate Julian Century using this online calculator? To use this online calculator for Julian Century, enter Julian Day (JD), Julian Day Reference (JD_ref) & Reference Time (t_ref) and hit the calculate button. Here is how the Julian Century calculation can be explained with given input values -> 0.012343 = (36892800-604800)/1.4.
