I would like to know the Earth Date or Julian Date of the Periapsis, Vernal Equinox or any other point in the orbit for every planet in the solar system excluding Earth.
A Julian Date is a continuous count of days and fractions of days since noon Universal Time on January 1, 4713 BCE, in the Julian calendar. It is commonly used in astronomy to simplify calculations of time and dates.
A Julian Date for a point in orbit is calculated by adding the number of days since the beginning of the year to the Julian Date of January 1, 4713 BCE. This number is then adjusted for the fraction of the current day, as well as any leap seconds that have occurred since the start of the year.
A Julian Date is used for points in orbit because it is a continuous count of time that does not reset at the end of each day. This makes it easier to calculate and track the exact position of an object in orbit without having to worry about the date changing at midnight.
Yes, a Julian Date can be converted to a regular calendar date using a conversion formula. However, this conversion is not always accurate due to variations in calendars and leap years.
A Julian Date is a count of days and fractions of days since noon Universal Time on January 1, 4713 BCE, while a Julian Day is a count of days and fractions of days since noon Universal Time on January 1, 4713 BCE, in the Julian calendar. The main difference is that a Julian Day includes a whole number for the day, while a Julian Date includes a fraction of a day as well.
