After 18 years, a rare alignment of the planets is happening as seven planets are aligning. This alignment would be the only one over the next many decades. According to astronomy experts, the alignment of three planets is called a conjunction. This is a regular event that occurs frequently. However, the alignment of seven planets is a rarer occurrence.
Seven planets namely Mercury, Venus, Mars, Jupiter, Saturn, Neptune, and Uranus will align beginning June 24 to June 26, the first conjunction of this scale.
