The tail of a comet is longest when the comet is?
The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.
How does a comet develop a tail?
a comet gets a tail as it gets closer to the sun, due to solar winds.
How far is Hayley's comet from the sun?
Hayley's comet is not always the same distance from the sun. This is because it has an elliptical orbit. When the comet is closest to the sun the ice begins to burn up forming the tail.
Which sun-orbiting body can approach Pluto the closest?
A comet can approach Pluto the closest, as can Neptune.
What affects does your sun have on coment's?
the comet gets repelled.
A comet's tail grows larger as it?
A comet (a dirty snowball) is a mix of ice, dirt and rock. It orbits is a wide oval coming closest to the sun at it's perigee It's apogee is it's farthest point. As a comet comes close to the sun, the ice sublimates (turns directly from ice into steam). When a comet comes closest to the sun the tail is largest.
What are the changes that occur as a comet orbits the sun?
it gets a tail
What causes a comet to have a tali?
cause it gets to close to the sun
How does a comet shine as it moves closer towards the sun?
the Sun's heat and radiation produce a wind called the Solar Wind, as a comet gets close to the Sun it begins to melt. ... This is when a comet begins to shine.
What pushes particles in a comets tail?
The pressure of the sun's light shining on the wispy gasses vaporizing from the comet's head push the tail of the comet away from the sun. While it looks like the "tail" of the comet is trailing behind, the tail always points away from the Sun. So after the comet's perihelion (the closest approach to the Sun) the "tail" is actually LEADING the comet!
A comet moves on an elliptical orbit around the Sun. Where is the comets velocity largest?
A comet's velocity is largest when it is closest to the Sun, a point known as perihelion. According to Kepler's laws of planetary motion, the comet accelerates as it approaches the Sun due to the gravitational pull, resulting in its highest speed at this closest point in its orbit. As it moves away from the Sun towards aphelion, its velocity decreases.
What is commet?
A comet is a ball of ice and dust that orbits the sun. As it gets closer to the sun, the heat and radiation from the sun cause the surface of the comet to be blown away, creating a tail that points away from the sun.
