Задание 16
Наблюдение суточного движения звёзд
Цель: убедиться в том, что положение звёзд на небе изменяется.
Порядок выполнения
Проведите наблюдение изменения положения на небе созвездия Большой Медведицы с интервалом 2–3 часа. Сделайте вывод.
Решение. Задание 16 (с. 219)
Цель: убедиться в том, что положение звёзд на небе изменяется.
Порядок выполнения:
Для выполнения задания в ясную ночь необходимо выполнить следующие шаги:
1. Найти на небе созвездие Большой Медведицы, которое легко узнать по характерной форме ковша.
2. Зафиксировать его положение относительно неподвижного объекта на Земле (например, дерева или крыши дома) и горизонта. Полезно будет сделать зарисовку или фотографию, отметив точное время наблюдения.
3. Через 2–3 часа провести повторное наблюдение с той же самой точки.
4. При сравнении будет отчётливо видно, что созвездие сместилось. Для наблюдателя в Северном полушарии оно совершит поворот против часовой стрелки вокруг Полярной звезды.
Вывод:
Наблюдение за созвездием Большая Медведица показывает, что его положение на небе, как и положение других звёзд, меняется с течением времени. Это видимое движение называется суточным движением звёзд. Оно является следствием вращения Земли вокруг своей оси. Из-за того, что Земля вращается с запада на восток, нам кажется, что звёздное небо вращается в противоположном направлении — с востока на запад, совершая полный оборот за звёздные сутки (приблизительно 23 часа 56 минут). Таким образом, цель задания достигнута: мы убедились, что положение звёзд на небе изменяется.
Ответ: Положение звёзд на небе меняется в течение ночи. Это видимое суточное движение — прямое следствие вращения Земли вокруг своей оси.
