Question

Like Earth, Venus and Mercury are planets, small, _____________ bodies that shine by ___________ sunlight. Venus is about the size of Earth, and Mercury is a bit larger than Earth's Moon. In this figure, they are both too ___________ to be seen as anything but tiny dots. The Sun is a ________, a _____-_____________ ball of hot gas that generates its own energy. The Sun is about _______ times larger in diameter than Earth (inset), but it too is nothing more than a dot in this view. Earth orbits the Sun once a _________.

Answer 1

Venus and Mercury are non-luminous planets that reflect sunlight, with Venus being similar in size to Earth, while Mercury is larger than the Moon but smaller than Earth. They appear as distant tiny dots. The Sun is a self-luminous star about 100 times larger than Earth, and Earth completes an orbit around it annually.
