No, the Sun is not moving closer to Earth. In fact, the Sun is slowly moving away from Earth at a rate of about 1.5 centimeters per year. This is due to the Sun losing mass through nuclear fusion, which weakens its gravitational pull on Earth.

While this movement is extremely slow, it's important to note that it doesn't pose any immediate threat to Earth. Over billions of years, the Sun's gradual movement away from Earth will have a noticeable effect on the planet's climate, but that's far in the future.

So, rest assured, the Sun isn't going to suddenly engulf Earth.
