  1. Star tracking of a star cluster in the summer sky.

    The Summer Sky

    The summer sky displays the wonder of the Summer Triangle, an astronomical asterism in the northern celestial hemisphere. The defining vertices of this imaginary triangle are at Altair, Deneb, and Vega. Each of which is the brightest star of its constellation (Aquila, Cygnus, and Lyra, respectively).

  2. A distant galaxy seen in the winter sky.

    The Winter Sky

    The Winter Triangle is an astronomical asterism formed from three of the brightest stars in the winter sky. It is an imaginary equilateral triangle drawn on the celestial sphere, with its defining vertices at Sirius, Betelgeuse, and Procyon, the primary stars in the three constellations of Canis Major, Orion, and Canis Minor, respectively.

    Our Solar System

    The Solar System is the gravitationally bound planetary system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, such as the five dwarf planets and small Solar System bodies.
