![]() ![]() Use + minutes if you increased the time to move the star onto the grid line and − minutes if you decreased the time. The response you submitted has the wrong sign. The time adjustment needed to position the star in the same location for one day forward is (g) How much did you change the time in minutes from exactly 24 hours later? Convert the change to decimal minutes:ĭecimal minutes = whole minutes + seconds (f) Noting the simulation time, carefully adjust the minutes (and seconds) so that the chosen star is back on the grid line. (e) Watching the chosen star, change only the date forward by one day at the same time, and notice that the chosen star is no longer on the grid line. (d) Adjust the time to move a chosen star onto one of the grid lines. (c) Click on the pause/unpause time icon to pause the time. (b) Click on the time/date in the lower right corner to display the time/date controls. (a) Turn on the Azmuthal Grid (Not the Equatorial Grid). Let's check if the stars are precisely back in the same location after 24 hours. Your response differs from the correct answer by more than 10%. What is the period of the right ascension scale's rotation in hours? Rework your solution from the beginning and check each step carefully. Your response differs significantly from the correct answer. What is the period of the right ascension scale's rotation in minutes? ![]() ![]() What is the angular speed of the right ascension scale in degrees per second? The angular speed in rotations per minute is What is the angular speed of the right ascension scale in degrees per minute?ĭid you accidentally divide or take the inverse in your calculation? degrees/minuteĬonsider the time for exactly one rotation. These answers have about 10% tolerance, so you will receive credit if you are within 10% of the correct value, which corresponds to approximately 2 significant digits. For example, change the time so that the 13h line is back where it started. (e) Adjust the time (try increasing or decreasing the hours) to rotate the right ascension scale and determine the time change required to make one complete rotation of the ascension scale. (d) Click on the pause/unpause time icon to pause the time (so the time only changes when you adjust it). Stellarium is a computer program that can help make astronomy and stargazing fun. (c) Click on the time/date rectangle in the lower right corner to display the time/date controls. This icon key shows all of these icons and labels their functions. Adjust the view so you can see some of the values on this scale. This scale is called the right ascension. (b) You can use the mouse to drag the grid left or right so you can read the scale on the grid. (a) Turn on the Equatorial Grid (Not the Azimuthal Grid) at the bottom of the screen. Do not choose Polaris or another star close to the center of rotation. Stellarium Mobile Free - Star Map 1.9.You can use the tools there to determine the rotational speed and period of a star you choose.Stellarium Mobile Free - Star Map 1.10.0.Stellarium Mobile Free - Star Map 1.10.1.Stellarium Mobile Free - Star Map 1.10.3.Stellarium Mobile Free - Star Map 1.10.4.Stellarium Mobile Free - Star Map APK versions (12): Detect planets, constellations, stars, and more.For more information on downloading Stellarium Mobile Free - Star Map to your phone, check out our guide: how to install APK files. Additionally, there is a dark mode that users may activate from the bottom menu to prevent eye fatigue during the night. Furthermore, they can change the landscape, display a grid, hide labels, and observe the celestial sphere from various cultural perspectives. Likewise, users are free to modify settings and insert a different set of geographical coordinates if they want to see what the sky looks like in other parts of the world at that time. Stellarium is a planetarium software that shows exactly what you see when you look up at the stars. The mobile solution detects location automatically as it aims to offer everyone the most accurate data. They can swipe left or right without a hassle, zoom in to check specific areas in detail, tap on any sky object that captures their interest, and read plenty of valuable information. When pointing their devices towards the sky, users get the chance to identify planets, constellations, stars, comets, artificial satellites, and more in just a few seconds. It has a beautifully-designed interface and provides lots of assets in the free version, along with some extra benefits available only after upgrading to a premium plan. The application addresses people of all ages who want to expand their astronomy knowledge. ![]()
