It is not necessary to add "the" before "Ocean Park" but you need to add "the" before all planets such as the Mars, the Earth, and the Venus.
We also need to add "the" before mountain ranges, seas, rivers and deserts such as the Himalayas, the Pacific Ocean, the Yellow River, the Sahara Desert.
With most names of people and places, we do not use "the". However, with some names of places, we need to add the definite article "the". These include: the United States, the United Kingdom, the People's Republic of China, the Philippines, the Netherlands.
Most names of countries do not use "the" such as Japan, France, Germany, Spain, India, Norway.
Frankly speaking, it is necessary for you to read more in order to remember the use of articlels and improve your English. There is no short cut.
