Well sweetie, astronomers use techniques like astrometry and spectroscopy to track the movement of those shiny little stars. When they observe a line of stars moving in a straight line, they're likely looking at a star cluster or maybe they just hit a cosmic traffic jam! Just sit back, relax, and enjoy the show, hun!
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
Astronomers use the Doppler effect to determine if a star is moving towards or away from us. By observing the shift in the star's spectral lines towards the blue end of the spectrum (blueshift) or the red end of the spectrum (redshift), astronomers can infer the star's motion relative to Earth. Blueshift indicates the star is moving towards us, while redshift indicates it is moving away from us.
Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.
the planet has moons or satellites orbiting around it. By observing the orbital motion of the moons, scientists can calculate the mass of the planet based on the laws of gravity and motion.
In observing a star, you can determine its brightness, color, position in the sky, and any variations in brightness over time. You can also analyze the star's spectrum to learn about its chemical composition, temperature, age, and evolutionary stage. By studying the motion of the star, you can infer its distance from Earth and its relative motion in space.

The motion along a straight line is known as rectilinear motion.
The trajectory of the motion is a straight line.
If an object moving along a straight line,path,track etc.It,s motion is said to be straight line motion
Isaac Newton was inspired to create his three laws of motion after observing the movement of objects around him, particularly the behavior of celestial bodies like planets and moons. He aimed to provide a comprehensive explanation for how motion works in the physical world, leading to the development of his groundbreaking laws of motion.
Astronomers determine the mass of the sun by observing the orbits of planets and other celestial bodies around it. They use Newton's law of universal gravitation and Kepler's laws of planetary motion to calculate the mass of the sun accurately. By measuring the orbital velocities and distances of objects in the solar system, astronomers can infer the mass of the sun through mathematical calculations.
I believe linear motion is simply straight motion because linear means straight
linear motion.
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
Rectilinear motion is motion along a straight line, while linear motion is motion in a straight line in any direction. Rectilinear motion is restricted to motion along a single axis, while linear motion can occur along any direction in a straight line.
Linear motion is motion along a straight line, where an object moves from one point to another in a straight path. Rectilinear motion is a specific type of linear motion where an object moves along a straight line with a constant velocity.
