Mars will soon begin its retrograde motion on Saturday, April 16. During its retrograde motion, It will seem like Mars is going on reverse, moving westward unlike its usual eastward path.

According to the report from National Geographic, the retrograde motion of Mars is due to the closer orbit and faster movement of Earth in its orbital track than the red planet.

During Earth's orbit around the sun, it catches up to Mars, creating an illusion that may make the red planet look like it is slowing down on its eastward motion. After the Earth passes the red planet, Mars will start to look like it is going to the west. Mars will retain its usual eastward motion once Earth is far enough.

Mars will be most visible in the sky a few hours before dawn. By mid-month, Mars will be sharing the sky with its rival, red supergiant star Antares, which means "equal to or rival of Mars."

The red planet will also be as twice as bright by the end of the month compared to the view we have seen in the beginning of April.

On the other hand, Jupiter will be accompanying our moon in the night sky this coming Sunday, April 17. Both of them will rise in the southeastern sky. They will appear to be five degrees apart from each other, about the width of three fingers held at arm's length.

Other sky phenomena to watch out for this April, according to the press release of NASA's Jet Propulsion Laboratory in Pasadena, California, is the Lyrid meteor shower.

Lyrid meteor showers, as per Space Weather, occur when Earth plows within the dusty tail of the Comet Thatcher. These dusts enter Earth's atmosphere at 49 kilometers per second, disintegrating as streak of lights.

The best time to view the Lyrid meteor shower will be before dawn on April 23.
