HOW COULD MEASURING THE ORBIT OF A COMET HELP SCIENTISTS UNDERSTAND WHEN IT WILL NEXT BE VISIBLE FROM EARTH?
PLease use lower-case letters as upper-case letters are considered impolite and are much harder to read!
Sra
Because comets, as planets, follow periodical orbits around the Sun. These orbitas are controled by KEPPLER'S LAWS. Use our Interactive Comet Animation to some things about how comets work.
Because comets follow periodical orbits around the Sun. As a comet’s orbit brings it close to the sun, we can see the tail. If we measure the orbit of the comet we will know the next time the comet is close to the sun.Also see Interactive Comet Animation about how comets work.
i think the same cause orbits are comets
Measuring the orbit of a comet can help scientists understand when it will next be visible from Earth because it provides important information about the comet's position and trajectory. By tracking the comet's orbit, scientists can predict its location in the future and determine when it will come close enough to Earth to be visible.
There are several steps involved in measuring the orbit of a comet:
1. Observation: Scientists use telescopes to observe the comet and gather data on its position in the sky over time. This involves recording the comet's celestial coordinates (right ascension and declination) at different dates and times.
2. Data Analysis: The observational data is then analyzed to determine the comet's motion relative to the stars. This information is used to calculate the comet's position and velocity in three-dimensional space.
3. Orbit Determination: With the positional and velocity data, scientists can calculate the comet's orbit using mathematical models and algorithms. This involves solving complex equations to determine the comet's trajectory around the Sun.
4. Predicting Future Apparitions: Once the comet's orbit is determined, scientists can predict when it will again come close to Earth and be visible from our vantage point. This is done by extrapolating the orbit into the future and calculating when the comet will reach its perihelion (closest approach to the Sun).
By understanding the comet's orbit and predicting its future apparitions, scientists can estimate when the comet will next be visible from Earth. This information is helpful for astronomers and skywatchers who want to observe and study comets, as it allows them to plan observations and anticipate when a particular comet will be at its brightest and most visible.
