Explain why the planets do not twinkle

The planets are much closer to us as compared to the stars. • Since the planets are closer to us, they appear much bigger and the light to come from more than one point. • The light coming from several points undergoes refraction also. • But this refracted light from several points cancels the twinkling effect . Hence, planets do not twinkle, due to their relatively large size and close distance from Earth.

Stars twinkle, planets do not. Planets appear to shine unwaveringly as a result of the distance between the planets. Even with high-resolution telescopes, stars look like mere dots, seeming to twinkle due to refraction when passing through the earth’s atmosphere. Planets, on the other hand, are much closer to the earth which appear as small discs through a telescope. Refraction is also observed in the case of planets when light from them enters the earth’s surface, but this light from both terminals of the planet repel away from each other in the opposite direction, nullifying their effect. Hence, they appear steady. Question Description Explain why the planets not twinkle? for Class 10 2023 is part of Class 10 preparation.

NCERT Solutions for Class 10 Science Chapter 11 - Do you know that the human eye has a lens in its structure? What is the function of this lens? Such interesting questions are answered with examples in NCERT Class 10 Science solutions chapter 11. Human eye is the most valuable and sensitive sense organ. Some of the topics which are covered in Human Eye and Colourful World Class 10 chapter are the human eye, defects of vision and their correction, refraction of light through a prism. NCERT Solutions for Class 10 Science Chapter 11 - Topic 11.2 Defects of vision and their correction: Q.1. What is meant by power of accommodation of the eye? Answer: The power of accommodation is the ability of an eye to focus near and far objects clearly and making image on the retina by adjusting its focal length. However, the focal length of the eye lens cannot be decreased below a certain minimum limit. Q.4. Answer: Since the student has difficulty reading the blackboard while sitting in the last row, he is most likely to suffer from the disease of myopia (short-sightedness) i.e., he can see the closer objects clearly but unable to see the far objects properly. Hence it can be corrected by placing the spectacles with concave lenses of appropriate power. The Human Eye and The Colorful World Exercise Solutions: Q.1. The human eye can focus on objects at different distances by adjusting the focal length of the eye lens. This is due to (a) presbyopia. (b) accommodation. (c) near-sightedness. (d...

• Refraction of Light • Observational Astronomy • Atmosphere Theory: When observing stars on a clear night, you can see them twinkle. As explained in the This is due to the fact that planets are much closer to the Earth than stars. Due to their relatively close distances, planets have a finite size when observing them from the Earth. Stars on the other hand, are so far away from the that we can only observe them as very small points of light. As such, a beam of light coming from a star appears much smaller than a beam of light from a nearby planet. The star's smaller light beam is more noticeably bent in the atmosphere, causing twinkling, whereas the light beam from a planet does not appear to move at all. This is why stars twinkle and planets do not. Apparatus: • Two lasers • Laser beam expander • Hot plate and a beaker • Water • Screen Procedure: • Fill the beaker with water and place it on the hot plate. • Outfit one of the lasers with the beam expander. This laser's beam will represent an observed planet. The laser without the expander will represent an observed star. • Set up both lasers side by side and place the screen so that the laser beams will hit it. Place the hot plate between the lasers and the screen so that the laser beams will pass right over the top of the beaker. • Turn the lasers and the hot plate on. • Turn of the lights and observe the position of the laser beams on the screen as the water starts to boil. The expanded beam should not move or change in...

Unlike stars, planets don't twinkle. Stars are so distant that they appear as pinpoints of light in the night sky, even when viewed through a telescope. Because all the light is coming from a single point, its path is highly susceptible to atmospheric interference (i.e. their light is easily diffracted). Planets are not a source of light. Instead, they reflect low intensity light reaching them.They are also closer to the Earth than the distant stars. Hence, the shift due to atmospheric refraction is smaller. As the planets are closer, planets appear larger in comparison to the stars. Hence, the shift is not enough for the planets to twinkle... hope it would be helpful✌? Planets do not twinkle because:1. Planets are not a source of light. Instead, they reflect low intensity light reaching them.2. They are also closer to the Earth than the distantstars. Hence, the shift due to atmospheric refraction is smaller.3. As the planets are closer, planets appear larger in comparison to the stars. Hence, the shift is not enough for the planets to twinkle.Twinkling occurs because the apparent position of a heavenly body is not fixed because the light through them is refracted through the atmosphere. Planets appear larger to human eyes as compared to stars because they are closer. As the angle subtended by the planets at the human eye is more, the shift in their position(as compared to stars) is smaller. Since, the shift is smaller, they do not twinkle.

The more atmosphere you are peering through, the more stars (or planets) appear to twinkle. Illustration by Stars twinkle, while planets (usually) shine steadily. Why? Stars twinkle because… they’re so far away from Earth that, even through large telescopes, they appear only as pinpoints. And it’s easy for Earth’s atmosphere to disturb the pinpoint light of a star. As a star’s light pierces our atmosphere, each single stream of starlight is refracted – caused to change direction, slightly – by the various temperature and density layers in Earth’s atmosphere. You might think of it as the light traveling a zig-zag path to our eyes, instead of the straight path the light would travel if Earth didn’t have an atmosphere. Planets shine more steadily because… they’re closer to Earth and so appear not as pinpoints, but as tiny disks in our sky. You can see planets as disks if you looked through a telescope, while stars remain pinpoints. The light from these little disks is also refracted by Earth’s atmosphere, as it travels toward our eyes. But – while the light from one edge of a planet’s disk might be forced to “zig” one way – light from the opposite edge of the disk might be “zagging” in an opposite way. The zigs and zags of light from a planetary disk cancel each other out, and that’s why planets appear to shine steadily. Astronomers use the term ‘scintillation’ to describe the twinkling of stars. Illustration via You might see planets twinkling if you spot them low in the sky...

Planets do not twinkle the waystars do, the reason is that stars are so far away that they appear to be a point source of light on the sky, while planets have finite size and the size of a planet "averages out" the turbulent effects of the atmosphere. Therefore, we see a relatively stable image to the eye. Hence, twinkling is not observed in planets.

Planet: • A planet is a celestial body that is revolving in an orbit around the Sun. • A planet has much mass for its self-gravity to overcome its own body forces so that it assumes a kind of equilibrium (nearly round) shape. • Examples are earth, Jupiter, and Saturn all orbiting around the sun. Planets don't twinkle: • The optical phenomenon of the twinkling of stars is due to atmospheric refraction. • The light coming from a far distance star is refracted through the atmosphere. • The twinkling of stars is caused by varying optical properties of air at a point which changes the path traveled by the beam of light coming from stars with time • Planets, do not twinkle because they are closer to the earth than those stars. Also, planets appear larger in comparison. • As the angle subtended by the planets at the human eye is more, the shift in their position(as compared to stars) is smaller. Since the shift is smaller, they do not twinkle. • Planets don't have their own energy, They reflect the light emitted by any star, Say the sun in our case. • So planets don't twinkle and the stars do. Therefore, planets do not twinkle due to their distance being less compared to a star.
